With the northern migration of the cold air from the north and the recent tropical storm landing on the 15th in our province, the sixth generation of late rice rice leaf roller and rice planthoppers are more likely to be outbreaks. Farmers must pay more attention to prevention and control. Control technical points:
1. Rice leaf roller (also known as Sanhua rice dumpling), to seize the peak application of young larvae, the first application time is September 17-18, the second application time is September 25-26. Mu can be used 15% of azodiazole EC 75 ~ 100 ml or 55% special kill 50 g or 20% triazophos 120 ml or 18% dichlorhydrone 200 ml + dimethoate 100 ml, watered 60 kg spray, fight drugs The amount of water should be enough to get wet.
2. Rice planthoppers (combined with Rhizoctonia solani): can use 25% Acetate water dispersible granules 3g or 25% fast-acting buprofezin 40g or 25% pymetrozine 20g + 30% emulsifiable concentrates 15 ml or 20% of the grain of the net or 25 grams of Jinggangmycin 200 grams, 60 kg of water spray.
In addition, we must also pay attention to rice blast, sheath blight, and bacterial leaf streak disease prevention. In the three days before the rice break, we can use 20% of the rice cultivars in the historical ward, growing green hybrid rice, and high quality rice fields. Tricyclazole 100g or 50% georgine 70g or 40% Fuji No. 65 to 100ml, water spray 60kg to control rice blast; bacterial streak disease medication methimazole or organic copper, copper (hydrogen Copper oxide) 800-1000 times spray.
