Which pesticide is used to control pollution-free corn pests and diseases
When using pollution-free sweet corn for pest prevention, the main strategy involves transplanting milk seedlings and applying early film coverage to effectively prevent damage from early-stage aphids, thus reducing economic losses. As explained by Xiaobian on China's Pesticide Network, here are the specific measures:
For the control of corn borers (2324, -10.00, -0.43%): It is recommended to introduce 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 enhance food safety. During the silking period, you can also apply a 5% Regent suspension diluted 1000 times, or a 25% chlorpyrifos solution at 1000 times dilution, or 48% chlorpyrifos at 100 ml per 100 liters of water. These methods have an overall control effect of over 90%.
For underground pests: Mix 250g of phoxim or 90% crystal trichlorfon with 5kg of water and spray it onto 100kg of chopped weeds to create poisoned baits. Spread these baits in the evening to attract and kill pests such as cockroaches, ground beetles, and ground tigers. If the infestation is at its peak during the larval stage, pesticide manufacturers recommend that most farmers use a 25% quick-killing emulsifiable concentrate diluted 1000 times, or a 52.5% agricultural emulsifiable concentrate also diluted 1000 times, and apply it evenly across the field.
In addition to these methods, regular monitoring of the fields and timely intervention based on pest activity levels are essential for maintaining a healthy crop without relying heavily on chemical inputs. Farmers are encouraged to combine both biological and chemical approaches for sustainable pest management. By adopting these practices, they can not only protect their crops but also contribute to environmental conservation and food safety.
