"Summary of the Field Efficacy Test Report for 20% Thiobacillus Copper SC (Lactococcus) - Paper Edition"
The 90% Thiobacillus original drug and 20% Thiobacillus Copper Suspension (Lonke), produced independently by Zhejiang Longwan Chemical Co., Ltd., successfully passed the technical review and expert evaluation conducted by the 8th National Pesticide Registration and Accreditation Committee under the Ministry of Agriculture. They were officially registered on December 29, 2008, with the official registration numbers PD20086025 for the 90% Thiobacillus original drug and PD20086024 for the 20% Thiobacillus SC (Lactococcus). These products received registration for controlling five diseases in three crops: Cucumber Bacterial Leaf Spot, Citrus Canker, Scab, Rice Bacterial Stripe, and Bacterial Blight.
In addition, Zhejiang Longwan Chemical Co., Ltd. submitted applications to expand the use of Thiobacillus thuringiensis (Loncobacteri) for three diseases in three crops, including Watermelon Wilt Disease, Cabbage Soft Rot, and Tobacco Wildfire Disease. The data has been accepted, with the administrative approval office number being 0309016566.
Beyond the official registration for crop control targets, many areas across the country have used copper thiobacillus (Lonkerella) for field disease prevention in crops not covered by the official registration. These applications have shown that the control effect on other diseases is also very effective. Xiong Xingping compiled and summarized the test results from standardized academic papers published in national journals as follows.

Key words: copper thiazolybdate; apple tree; rot disease; rotenone; trial; efficacy
Apple tree rot is a devastating disease that mainly affects trunks, main branches, and larger lateral branches, causing serious orchard damage. Trees become sick, branches are incomplete, and even dead trees can occur, which hinders fruit tree production. To explore new ways to prevent apple rot, we introduced the thiazole organic copper bactericide Dragon's Bacteria (thiabendron) in 2006 to test its prevention and control effects on apple rot disease and determine the appropriate application methods and dosage, providing a scientific basis for large-scale promotion.
The recurrence rate of lesions treated by bronchobacillus was significantly lower than that of the control agent "multiple-effect decending rot." Additionally, through investigation, the prevention and treatment of ringworm disease by bronchobacillus showed some effect, achieving both cure purposes.
Summary: The test results showed that 20% of the bronchobacillus sp. suspension was safe for fruit trees within the tested concentration range. Application method: Before germination, the spring fruit tree is smeared with 30-50 times liquid of dragon's bacterium (thia copper) and then sprayed once with 200 times of dragon's bacterium (thiacax) to have a good control effect against rot. It is an ideal agent to replace high-residue pesticide Formamate and is worth promoting in a large area.

6. Screening test for the control of bacterial base rot of rice
Published in Pesticides Vol.42 No.2, 2003. Liu Anmin Tao Xiuzhen (Fujitai County Plant Protection Station, Yutai, China).
Abstract: Field trials have shown that four fungicide types such as dragon's bacillus (copper thieno), copper (copper hydroxide), clobetasol (mycin), and streptomycin for agricultural use control bacterial root rot of rice. The effect can reach more than 66%, superior to chlorella bromide (chlorobromoisocyanuric acid) and carbendazim, etc., and can greatly reduce the diseased plant rate, the effect of increasing production is obvious, and can be further promoted in production in the future.
Key words: bacterial base rot; bactericide; copper thiate; rice; control effect
Bacterial base rot of rice is an important disease that occurred in rice in our county in recent years. It can develop from the tillering stage to the panicle stage. Because it is soil borne, the infection is fast, and at present there is no high disease in our county. Resistant varieties, therefore, caused great losses to rice production in my county. In addition to strengthening the cultivation of rice in order to improve its own resistance, how to screen out effective agents for the prevention and treatment of this disease is particularly important. I stationed in 2002 in our county a large number of seven kinds of fungicides used to control the disease, conducted a field efficacy comparison test, and achieved good results.
The results of the plot test showed that the 20% Runicillus sp. suspension was the most effective, reaching 78.7%, 77% of the copper from the crown bacterium, 3% of the konjac, 10 million units of the agricultural streptomycin, and 6% The relative control efficacy of carbendazim and 50% of thiobacillus was between 60% and 70%, while the control effect of 50% carbendazim was the worst, only 22.9%. This shows that 20% of Longkei (thiacax copper), 77% of copper, 3% Kechuang, 10 million units of agricultural streptomycin and other agents can be used in our county.
Summary and discussion: Through the field screening test of rice bacterial rot caused by the above-mentioned seven agents, it can be seen that the copper preparations such as Longkei (copper thiazole) and copper (copper hydroxide) have obvious protective effects. The control efficacy of biocides such as Kezikang (biomycetin) and agricultural streptomycin is also higher than some common drugs. At the same time, through the investigation during the trial, it can be found that the application of these fungicides can significantly delay the onset of the disease, reduce the incidence of the disease, greatly reducing the rate of diseased plants, and thus play a very satisfactory increase in production efficiency. It is promoted in actual production. In the test process and other demonstration experiments, it was found that inorganic copper preparations such as copper (copper hydroxide) of the crown bacterium were applied at high temperatures, and they could cause slight phytotoxicity to rice, so they should be avoided in the high-temperature period. Bacterial base rot of rice should be mainly prevention. It must be applied before the onset of rice, otherwise it will affect the effect. If the rice is applied every 7 to 10 days before transplanting, tillering, and early heading, the effect will be even better.

Thiodiazole-copper is a new type of thiazole organic copper bactericide independently developed in China. It was first approved by the Ministry of Agriculture in 2000 for the temporary registration of pesticides. Its chemical name is 2-amino-5-mercapto-1,3,4-thiadiazole copper complex, the main metabolite is thiadidine (AMT), the structure is shown in Figure 1, so this experiment is to determine Thiadiazole residue as a quantitative basis. The drug is highly effective, low-toxic and safe, and it is highly effective in controlling bacterial and fungal diseases of crops. It is effective in controlling watermelon wilt disease. At present, there are no corresponding national and ministerial standards for the detection methods of residues, and there are no reports in foreign countries. Therefore, a method for the determination of copper residues in watermelon has been established in this paper. The establishment of the monitoring system has practical significance for monitoring its use in fruits and vegetables, formulating its maximum residue limit (MRL), and protecting human health. The method has the advantages of simplicity, accuracy, high sensitivity and good repeatability.
The watermelon grown in greenhouses was sprayed with pesticides, then collected into long-term and harvest watermelon samples, and stored frozen at minus 18 degrees before measurement. Samples were treated according to the method of “sample pretreatment and enrichment and purification of thiadiazoleâ€. The copper content of Thiobacillus in the long-term watermelon was calculated to be 0.256~1.078 mg/kg; the copper content in the harvested watermelon was always Not detected. It showed that the degradation rate of copper thienobacterium in watermelon was faster and it was safer for humans.

Abstract: Ginger disease is the main disease on ginger, and it is also the biggest obstacle to ginger production. From 2002 to 2004, we used 20% Thiobacillus copper for chemical control tests and different application methods. The results showed that there was a good protection and treatment effect against ginger borer, and the highest control effect was 67.61%. The method of use is to soak the seeds with 500 times copper thiazolyl, and simultaneously irrigate the roots three times with thiazolyl copper 500 times in the growth period, and control them once every 10 days.
Key words: copper thienobacterium; ginger; rot disease; control; trial
Ginger rot, commonly known as ginger borer, is caused by the infection of Pseudomonas solanacearum Smith and is the most common and most harmful disease on ginger. The incidence rate of ginger aphid disease in Shandong Province is 20% to 30%, and the general incidence of land parcels is reduced by 10% to 20%, and more than 50% of them are severe, even out of production. This is a major factor restricting the development of ginger production.
Ginger disease (rot disease) is a bacterial disease. The pathogen is Psetum mongolicum Psetudomonas solanacearum (Smith) Smith. It can infect not only ginger but also solanaceous crops such as tomatoes, eggplants, peppers and potatoes. Pathogens mainly in winter in the roots and soil, generally in the soil can survive for more than 2 years, with the strain of ginger is the main source of primary infection, and can use the ginger to adjust the operation of long-distance transmission. In the onset of ginger fields, the soil in which the remnants of diseased plants were left behind caused soil contamination and the diseased soil was also an important source of infection of ginger borer. In addition to diseased ginger and diseased soil, the use of sick or diseased soil fertilizers in ginger fields will also bring the disease to the field. Irrigation water, rainwater, and underground pests are also the vectors that spread germs. Germs are invaded by wounds from roots and stems. They enter the vascular bundles from the parenchyma and rapidly expand, eventually causing the whole plant to dry up.
With the adjustment of industrial structure, the growing area of ​​ginger has been continuously increased, and the number of planting plots has increased year after year. The occurrence of ginger borer disease has also been aggravated and has become the most important disease in ginger production. In order to screen for suitable drugs for controlling ginger acarid, 20% Thiobacillus copper suspension (Loncobacter) produced by Zhejiang Longwan Chemical Co., Ltd. was subjected to a pharmaceutical control experiment.
Because the control effect of irrigating roots with 300 times liquid and irrigating roots with 500 times liquid is almost the same (average control efficiency is 70.61% and 69.13%, respectively), taking into account the cost of pesticides used by farmers, it is recommended to promote the use of 500 times liquid in production. . The method of use is 500 times liquid soaking of dragon's fungus, another dragon's fungus (thiaca copper) 500 times the growth period irrigate 3 times, interval 10 days. However, during the growth period, the pesticide should be used at the beginning of the disease. After soaking and irrigating the roots during the growing period, it was discovered that the dragon's fungus (thiaca copper) had no adverse effects on germination, emergence, and growth of ginger, and was safe to ginger, and the dragon The ginger treated with Gram-negative copper (Cu-Bacillus spp.) emerged neatly after planting. According to the survey, the uniformity of emergence of ginger in the treated area of ​​Longkei (Thiococcus spp.) increased by 8 percentage points compared with the control, and the plants grew robustly and the leaves were dark green. The main stem of the seedlings was 5.7 cm higher than the control. This may be because the ultrafine particles of the dragon bacteria are easily absorbed by ginger and can effectively supplement copper. Has a significant role in promoting growth, but further research needs further research.
Conclusion: The bronchobacillus bronchiseptica has a good protective effect on ginger aphid, and it is recommended to promote it in production. Rhodendron 500 times liquid soaking, while in the growing period 500 times liquid continuous rooting 3 times (10 days interval), but the growth phase of the application should be mastered in the early onset of administration.

For a long time, the bactericides used in citrus production in China are mainly inorganic copper preparations based on Bordeaux mixture and benzimidazoles represented by thiophanate. However, the traditional inorganic copper agent Bordeaux has many disadvantages in the use of oranges, such as the occurrence of orange rust, which affects photosynthesis, and can not be mixed with other pesticides and alternate with other pesticides. Etc.; Benzimidazole agents represented by thiophanate, which has been used in recent years, have been resistant to drugs and their efficacy has dropped significantly. There is no need for new pharmaceutical products to replace or alternate use of the above-mentioned agents in production.
In recent years, there have been many new varieties of copper preparations at home and abroad. The evaluation of the application performance of new pesticides can be summarized as the efficacy of the target; the safety of humans, plants, natural enemies and the environment when used; and the non-target diseases Insect mutual interference. According to available data, the patented new product Thiopenthromycin (Loncobacter) has excellent control effects on citrus canker and scab, and it has a wide application prospect in citrus production. However, the effect of the agent on the reproduction of T. citrifolia is not clear, and the author conducted a research on this from 2OOO to 2001.
Conclusions and Discussion: In this study, the influence of the chemical agent on the reproduction of the whole clawed X. The results showed that the LC50 concentration of copper thiazolybdate to quinquefascia gracilis was 506.17 mg/L, and the LC90 concentration was 34 817.69 mg/L. Pharmacological treatment of female nymphs using 667, 333, 167, 83, 42mg / L and other five concentrations, the results found that the survival rate of female adult pupa, two high-concentration treatment inhibited it, three low-concentration treatment has enhancement. In these five concentrations, the difference between treatments did not reach a significant level. The females treated with the above concentrations had their egg production inhibited to varying degrees, but the difference did not reach a significant level. The effect of 400mg/L egg on its hatching had obvious promoting effect in the early stage, and had obvious inhibitory effect at the peak and the end of incubation. On the basis of the above tests, the total population of T. japonica on potted seedlings was treated with the common concentration of the agent (400 mg/L). After 50 days of observation, the difference between the population of insecticides in the pesticide and the control group did not reach the test concentration range. Significant levels.
In conclusion, the results of the study showed that within the range of experimental concentration (400 mg/L), copper thiophene (Loncobacter) did not induce or promote adverse effects on survival and reproduction of C. citrinopileatus.

Published in "Hubei Plant Protection," 2007 No.3Hubei Plant Protection. Cui Ming Zhao Xingxi Zhang Longzhi (Ankang Plant Protection Station, Shaanxi Province).
Abstract : In order to find new effective and low toxic agents for controlling soft rot of konjac, timely guidance of field prevention and control work. The plant protection station of Ankang City, Shaanxi Province, introduced the konjac continuous cropping plot in the Maoba Village of Hehe Township in Hanbin District for the prevention and control experiments.
The test results showed that the control effects of baptizing and dragon's fungus on konjac's soft rot were better, and that baketin was better than that of dragon's fungus when it was controlled once; while it was twice that of dragon's fungus, bacron was better than baxtin (77% of copper hydroxide) ), The two agents can be used interchangeably in the field to prevent germs from developing resistance and improve the control effect. Agricultural streptomycin is commonly used as a medicament for the control of soft rot. It takes a long time to use. In severe years of konjac soft rot and continuous cropping, the control effect is poor. The enemy has a poor effect on the control of konjac soft rot, and should not be promoted in production.

Abstract: In this paper, several agents were used to control citrus canker disease. It was concluded that dragon's bacillus (thiacax), Garenon (Chunleiwang copper), streptomycin for agriculture, and bactericide (53.8% DP) were available. In a large area of control of citrus canker disease, control should be used alternately.
Key words: citrus; ulcer disease; drug test; Taihe county
In recent years, citrus canker disease in Taihe County has been severe, with an annual bias towards re-emergence, which has caused heavy losses to citrus production in the county. At present, there are many kinds of agents for the control of citrus canker in the market, and the quality is uneven. In order to explore the prevention and treatment of citrus canker disease, and provide a basis for large-scale promotion, we conducted a pharmacy test on red tangerine in 2008. The experimental medicaments Dragon's Bacteria (thiacax), Garenon (Chunleiwang's copper), agricultural streptomycin, 53.8% kill (copper hydroxide DP), Yeqingshuang (Yetzol) can be used to control citrus canker disease The control effects were 87.24%, 85.01%, 81.54%, 80.41%, 73.59%, respectively. Tests on the control of citrus canker by several agents have led to the conclusion that, when a large area is used, the use of dragon's fungus (thiacax), Garenon, and streptomycin for agriculture can be promoted and used alternately. Concentration can be designed according to the experimental concentration. Spraying the first drug when the shoot length is 1.6-3.3 cm, spraying the second drug after 10 days, can effectively control the hazard of citrus canker.
