Do a good job in the control of rice "two migratory" pests

Prevention and control opinions

Single cropping rice was comprehensively controlled from July 13 to 15, mainly for leaf roller and white-backed planthopper, as well as gray planthopper and rice thrips. The pesticide formula was as follows: 1. 5% fipronil (Regent) suspension 40-50 ml per mu; 2. 31% fipronil triazophos (Sanfu) 70-80 ml per mu; 3. 50% Daofengsan 100 ml per mu. 4. 40% chlorpyrifos (Xinnongbao, Saiben) 50 ml plus 80% fipronil (Regent) water dispersible granule 2 grams per mu; 5. 30% chlorpyrifos (Lianzhongning) 80 ml plus 5% fipronil (Regent) suspension 20-30 ml per mu. Either of the above agents add 10% imidacloprid (thumb, Bidan) 40g / mu flushing 30kg spray. "Jixiaoli" adjuvant can be added to improve the control effect.

Points for attention

1. Apply the pesticide after the dew dries in the morning and evening. If the prevention effect of rain after the medicine is poor, it should be treated immediately.

2. The spray quality of leaf borer is the key, the finer the spray is, the better the spray effect is, and the spray effect of the manual sprayer is better. If the manual sprayer uses only one spray hole and the diameter of the spray hole is 1 mm, the water consumption can be reduced appropriately.

3. The above formulations should be used alternately to avoid resistance caused by long-term use of the same agent. At the same time, the use of pyrethroids pesticides in rice fields is prohibited.

4. Fipronil (fipronil) is highly toxic to @ # @ 255 crab, shrimp and crab, so pay attention to the safety of use and pay attention to the safety of sericulture during application.
