For people to pay attention to the heatstroke prevention and cooling work under high temperature weather, we must make four guarantees: to ensure the safety of pesticide application personnel; to ensure the safety of crops; to ensure environmental safety; to ensure the prevention and control of pests and diseases.
In order to do these 4 guarantees, we need to pay attention to:
1. Select high-efficiency, low-toxicity and low-residue pesticides. At present, many rice varieties enter the peak or late stage of the tillering, which is a key period for the prevention and control of sheath blight. For the control of sheath blight, you can choose Artemis, Ou Bo, Ou De, Zumbo, etc. Pharmacy, rice blast can choose 9% of Daqing or Ami seconds to receive, take enemy stability, rice blast and other agents.
Most of the corn is in the big bell stage, mainly need to control the second generation of corn mash, you can choose chlorantraniliprole, sword (chlorinated benzamide compounding agent), a vitamin salt or a complex of vitamin A Formulation.
Soybeans or peanuts should pay attention to the occurrence of cockroaches. When cockroach hatching, you can choose biological agents such as Beauveria bassiana or Metarhizium, which are safe for humans and animals and have no pollution to the environment. Soybeans and three generations of cotton bollworm, Spodoptera litura can also choose chlorantraniliprole and other compounding agents.
2. Be sure to use enough water to make enough water to ensure the effect of prevention and control.
3. Use the medicine in a suitable period of time, preferably in the morning and evening. The high temperature season is before 11 o'clock, and it is more appropriate to fight drugs after 4:30 in the afternoon. When the temperature is high, the pests will enter the high temperature dormancy or drill into the crop, and many of the chemicals will be easily decomposed when they see the light, and the efficacy will be greatly reduced. The high-temperature liquid will also evaporate, and the evaporated gas will easily enter the human body, so it is necessary to avoid the high-temperature period of time to fight drugs.
