Corn field to control ash planthoppers to prevent injury

When the cornfield plant is infested in the corn field, it is usually necessary to use a large amount of medicine frequently to control the amount of insects. In recent years, accidents caused by improper use of drugs in the production of corn have caused frequent occurrence of accidents. Therefore, safe medication should be taken care of when controlling SBPH.

The use of organic phosphorous fly hoppers in corn fields in the cornfields often requires frequent and large doses of pesticides to control the amount of insects. In recent years, accidents caused by improper use of drugs in the production of corn have caused frequent occurrence of accidents. Therefore, safe medication should be taken care of when controlling SBPH.

When using organic phosphorus and pyrethroid pesticides in corn fields to control SBPH, the chemical concentration should be strictly controlled, otherwise it is easy to produce phytotoxicity. For example, 48% chlorpyrifos emulsifiable concentrate is generally used for 2000 times, and the dilution ratio can not be less than 1000 times; pyrethroid pesticides are generally used for 2000 to 3000 times. Dichlorvos, phoxim and fenvalerate are prone to phytotoxicity on corn and are generally not to be used.

When pesticides like pyrethroids and pyrethroids are used to control SBPH, the concentration of the drug solution should be strictly controlled, otherwise it is prone to injury. For example, 48% chlorpyrifos emulsifiable concentrate is generally used for 2000 times, and the dilution ratio can not be less than 1000 times; pyrethroid pesticides are generally used for 2000 to 3000 times.
