The success or failure of rice pest and disease control plays a vital role in rice yield. For the control of rice pests and diseases, first, select varieties resistant to pests and diseases; second, fertilize reasonably, applying more organic fertilizer and phosphorus and potassium fertilizer; third, use water scientifically, keep the field dry, and during the rainy period pay attention to clearing ditches and draining water; fourth, use chemical control correctly. Below are common chemical control methods for rice pests and diseases, in the hope of making a modest contribution to increasing the rice yield of rice growers in 2012.
1. Control of rice blast: Rice blast, also known as rice fever, commonly called fire blight, hanging-head blight, neck-pinching blight, etc., mainly damages the aboveground parts of the host plant.
(1) Control of leaf blast: When lesions appear in the field, use 100 grams of 20% tricyclazole wettable powder, diluted with 45 kg of water for spray control; 15 ml of 30% Jiemiao emulsifiable concentrate, diluted with 45 kg of water for spray control; 50% sulfur triazole 200-250 ml/mu, applied twice in succession, once every 5-7 days.
(2) Control of ear blast: The best time to control rice blast is 2-3 days before heading, with the following chemical options:
75% tricyclazole wettable powder, 30 grams per mu;
40% Fuji No. 1 emulsifiable concentrate, 150 ml per mu;
21.2% JIASHOUREBI, 100 grams per mu.
