Which pesticide is used to control pollution-free corn pests and diseases
When using pollution-free sweet corn for pest prevention, the primary methods involve transplanting milk seedlings and applying early film coverage to effectively prevent damage from aphids in the early stages, thus reducing economic losses. According to Xiaobian from China's Pesticide Network, here are some specific measures:
For the control of corn borers (2324, -10.00, -0.43%), it is recommended to inoculate Trichogramma eggs during the big bell stage, which is an ideal method for biological control. Alternatively, high-yield and residue-free pesticides can be used to ensure food safety. During the silking period, mites can be controlled using a 5% Regent suspension diluted at 1000 times, or a 25% chlorpyrifos emulsion diluted at 1000 times, or 48% chlorpyrifos at 100 ml per 100 liters of water. These methods have an overall control effect of over 90%.
For underground pests, a mixture of phoxim or 90% crystal trichlorfon (250g) dissolved in 5kg of water can be applied to 100kg of chopped weeds to create poisoned baits. These baits should be scattered on the ground in the evening to attract and kill pests such as cockroaches, ground beetles, and ground tigers. If the larvae are at their peak, the pesticide manufacturer recommends that most farmers spray a 25% quick-killing emulsifiable concentrate diluted at 1000 times, or a 52.5% agricultural emulsifiable concentrate also diluted at 1000 times, for full coverage treatment.
These integrated pest management strategies not only help protect the crop but also promote sustainable farming practices by minimizing chemical use and ensuring safer produce for consumers. By combining biological control with targeted pesticide applications, farmers can achieve effective and environmentally friendly pest control.
