Soybean borer is a significant pest that affects soybean crops during the pod blasting stage. The larvae feed on the developing grains, causing damage that can significantly impact both yield and quality. On average, the infestation rate ranges from 5% to 10%, but in severe cases, it can reach up to 50%. It is crucial to implement effective control measures as soon as possible to minimize losses.
The best time for prevention is between 3 p.m. and 5 p.m., when a sudden increase in moth activity is observed—this often indicates mating or swarming behavior. This period is ideal for taking action to reduce the population before it becomes too high.
For biological control, one effective method is the release of Trichogramma wasps, which parasitize the eggs of the soybean borer. It is recommended to release 20,000 to 30,000 Trichogramma per acre at the peak of egg-laying. This practice can reduce the infestation rate by approximately 40%. Another option is the application of Beauveria bassiana, a fungal biopesticide containing 2.5 billion spores per gram. Apply 1.5 kg per mu (approximately 0.67 acres) before the larvae move, which helps to infect and kill them effectively.
Chemical control methods are also available. One approach is fumigation using dichlorvos. Mix 80% dichlorvos emulsifiable concentrate at a rate of 100–150 ml per acre. Soak two sections of sorghum or corn stalks, peeling one part while leaving the other intact. Once soaked, insert the stalks into the rows every 5 to 6 meters across the field. Another method is foliar spraying. Use 12.5% deltamethrin EC at a rate of 50 kg of water per acre, or 5% Fortune Chrysanthemum EC with the same volume of water. These sprays help to target the larvae directly and provide effective control when applied properly.
Early detection and timely intervention are key to managing soybean borer infestations. Combining both biological and chemical methods can lead to more sustainable and long-term solutions for farmers. Always follow safety guidelines when handling pesticides and ensure proper application techniques for maximum effectiveness.
Probiotics are a kind of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. Such as organic probiotics powder, Digestive Health Probiotics, Multi-Strain Probiotic Powder, and Probiotic Supplement Powder By regulating the host mucosa and the immune function of the system or by regulating the balance of intestinal flora, promoting the absorption of nutrients to maintain intestinal health, thus producing single microorganisms or a well-defined mix of microorganisms that are conducive to health effects.
Probiotics Powder has many benefits. It's a Nutritional Supplements.
Probiotics can synthesize digestive enzymes. Together with the digestive enzymes synthesized by animals, they participate in the digestion of nutrients in the intestine, stimulate the secretion of digestive enzymes in the animal body, reduce the depth of the small intestine recess, increase the villi height, increase the surface area of the small intestine, and promote the absorption of intestinal nutrients. Probiotics can also be used as Food Additives.
Probiotics' structure, such as peptidoglycan, lipoteichoic acid, and other components, can act as antigens to directly activate the immune system, or stimulate the host immune system through autocrine immune activators, thereby improving the immunity of animals, enhancing the activity of the body's innate immune cells and natural killer cells, activating dendritic cells, and stimulating the body to produce cytokines. And stimulate B cells to secrete antibodies, probiotics can stimulate the gut to produce secretory globulin A (SIgA), and protect body health.
