1. Seriously implement 3 preventive measures before sowing rice. 1.1 Resistant to rice blast varieties according to local conditions. Early rice should be planted as far as possible. Jinyou 402, You I402, Jinyou 974, Zhongyou 974, You I66, Zhongyou 752, Jinyou 752, 65002, Xinxiangyou 80, Honglian No. 6 and other susceptible varieties. 1.2 Cultivate winter free fields and winter crop fields early in the spring to reduce the source of aphid insects. They asked Weinan to finish farming before April 1st, before April 10th in Yuzhong, and before April 15th in Yubei. 1.3 Do a good job of seed treatment to reduce the occurrence of pests and diseases. Early rice mid-season seeds are soaked with 2000-3000 times solution of 25% imidamide for 48 hours to direct germination to prevent rice blast and bakanae disease. The middle and late rice seeds were prepared with 10% imidacloprid wettable powder 40 grams, and then sowed directly after the buds were mixed to prevent the control of horses and foals. 2. The seedlings shall be sprayed with super-fed herbs 3-5 days before transplanting to prevent or reduce the occurrence of pests in the field during the tillering period. 2.1 Early rice fields: 40% per acre sprayed with 100 ml of chlorinated emulsifiable concentrate or 60 ml of 5% Regent suspension to prevent and reduce the occurrence of second generation warts in Daejeon; 75% per acre sprayed WP 60g Or 20% tricyclazole powder 200 grams, to prevent field leafhoppers. 2.2 Medium Rice Fields: Prevention of Sapium Tuberculosis and Leaf Mites: 40% of the planting area is sprayed with 100 ml of chlorinated emulsifiable concentrate (100 ml) or 5% of Regent® suspension concentrate (60 ml) to prevent and reduce the occurrence of the second generation of worms in Daejeon; WP 60g or 20% tricyclazole powder 200g, to prevent field foliar. Mu spray 10% imidacloprid wettable powder 40 grams to prevent field rice planthoppers, rice thrips. 2.3 Late rice paddy fields: 40% per acre sprayed with 100 ml of chlorinated EC to prevent and reduce the occurrence of field locusts. 3, from the tilling to the booting stage to focus on control of aphids, mixed drugs and other diseases and pests. Early rice in the middle and late May to prevent the generation of II pupae, the use of rice field treatment of dry sheathing rate of more than 8% of the prevention and treatment, focus on spraying leaf sheath, during which found that leafhoppers, especially the center or acute lesions, timely control of pesticide application. Late rice is controlled on or after August 10, or 10-15 days after planting, to prevent or treat S. japonicum or S. japonica. When controlling aphid application, Jinggangmycin was added to prevent sheath blight. 4, break the heading period mixed drug preservation. The implementation of mixed medication, a variety of pests and comprehensive management. Early rice focuses on the prevention and treatment of panicle blast, simultaneous treatment of sheath blight, and rice planthoppers; middle rice focuses on controlling aphids and panicle blasts, taking into account rice planthopper and sheath blight; late rice hosts aphids, taking care of sheath blight and rice planthoppers. In the period of heading and heading, during the period of heading and fruiting, the Jinggangmycin was added to prevent and control the sheath blight, and the common areas of rice planthoppers should also be added with the help of Gao Longgong to prevent and control rice planthoppers; The diseased cultivars were treated with rice Quqing in the early stage of snoring (dachating period), and the main descending area of ​​rice leaffolder was used for the prevention and treatment at the earliest stage of late rice, the late stage of tillering of middle and later rice, and the jointing booting stage. 5. During the harvest period, the rice is cut into the mud and the rice in the early rice is harvested in time.
