种衣剂对水稻发芽的影响及病虫害防控试验

Effects of Seed Coating Agents on Rice Germination and Disease and Pest Control

本文研究了11%精甲·咯·嘧菌种子处理悬浮剂、350 g/L精甲霜灵种子处理乳剂、25 g/L咯菌腈悬浮种衣剂、10%嘧菌酯悬浮种衣剂等4种杀菌种衣剂,以及60%吡虫啉悬浮种衣剂、50%氯虫苯甲酰胺悬浮种衣剂、30%噻虫嗪悬浮种衣剂、35%丁硫克百威悬浮种衣剂等4种杀虫种衣剂对水稻发芽和根系生长的影响以及防控恶苗病、稻蓟马的效果。结果表明:除了35%丁硫克百威悬浮种衣剂外,4个杀菌种衣剂和3个杀虫种衣剂对水稻发芽率、苗高、根长均有一定的抑制作用;60%吡虫啉悬浮种衣剂和30%噻虫嗪悬浮种衣剂保叶效果优于50%氯虫苯甲酰胺悬浮种衣剂、35%丁硫克百威悬浮种衣剂。

This paper studied the effects of four kinds of bactericidal seed coating agents(11%metalaxyl-M·fludi-oxonil·azoxystrobin ZX,350 g/L metalaxyl-M ES,25 g/L fludioxonil FS and 10%azoxystrobin FS)and four kinds of insecticidal seed coating agents(60%imidacloprid FS,50%chlorantraniliprole FS,30%thiamethoxam FS and 35%carbofuran FS)on rice germination,root growth and the control of rice bakanae disease and rice thrip.The results showed that except 35%carbofuran FS,four kinds of bactericidal seed coating agents and three kinds of insecticidal seed coating agents had a certain inhibitory effect on rice germination,seedling height and root length.60%imidacloprid FS and 30%thiamethoxam FS had better leaf protection effect than 50%chlorantraniliprole FS and 35%carbofuran FS.
