近年来,杀菌剂使用量在逐年增多,呈上升趋势。2010年中晚稻病害总体呈偏重发生态势,以稻瘟病、纹枯病为主,发病面积2.88亿亩。过去常用的防治稻瘟病的杀菌剂如稻瘟净、异稻瘟净因长期使用效果已不理想,以后用稻瘟灵(富士一号)、三环唑等取代,因作用方式比较单一,多年使用病菌易产生抗性,防治效果逐年下降。2010年一些新型的高效药剂如灭病威(多菌灵与硫磺复配而成)、乙蒜素(又名抗菌剂402)、醚菌酯等在防治稻瘟病中需求量上升。防治水稻纹枯病主要用井冈霉素,井冈霉素
In recent years, the amount of fungicide used is increasing year by year, showing an upward trend. In mid-late 2010, the overall disease appeared to be serious, with rice blast and sheath blight as main symptoms, and the disease area was 288 million mu. In the past commonly used in the prevention and treatment of blast fungicides such as rice blast net, different blast caused by long-term effect is not ideal, after the use of blast star (Fuji), tricyclazole and other substitutions, because the mode of action is more single, The use of bacteria easy to produce resistance, prevention and control effects decreased year by year. In 2010, some new-type and high-efficiency drugs such as vanilloprazole (carbendazim and sulfur compound), ethylicin (also known as antibacterial agent 402) and kresoxim-methyl are in increasing demand in the control of rice blast. Control of rice sheath blight mainly Jinggangmycin, Jinggangmycin
