摘要
阿维菌素是一种具有杀虫、杀螨、杀线虫活性的十六元大环内酯化合物,具有结构新颖、农畜两用、抗性产生缓慢、触杀、胃毒、渗透力强,无致畸、致癌、致突变作用等的特点,是当前生物农药市场中最受欢迎产品之一.为了探索 0.5%阿维菌素液体药肥对番茄抗根结线虫病及其促生应用技术,将 0.5%阿维菌素液体药肥配制成不同浓度溶液,在室内进行了抑制线虫活性测定;并对盆栽番茄进行冲施,观察并记录番茄根结线虫病发生情况及农艺性状指标变化.研究表明,0.5%阿维菌素液体药肥对根结线虫有击倒能力和致死能力.稀释 800 倍时,番茄农艺性状各指标达到最高.因此,推荐 0.5%阿维菌素液体药肥使用浓度为稀释 800 倍,此时番茄抗根结线虫病和促生效果最优.
Abstract
Abamectin is a hexadecyclic macrolide compound with insecticidal,acaricidal and nematicidal activities,which has the characteristics of novel structure,dual use of agriculture and livestock,slow production of resistance,contact killing,stomach toxicity,strong penetration,no teratogenic,carcinogenic and mutagenic effects,and is one of the most popular products in the current biopesticide market.In order to explore the application technology of 0.5%avermectin liquid fertilizer on tomato root-knot nematode disease resistance and its growth-promoting technology,0.5%avermectin liquid fertilizer was prepared into different concentration solutions,and the activity of nematodes inhibition was measured in the laboratory,and the potted tomatoes were washed to observe and record the occurrence of tomato root-knot nematode disease and the changes of agronomic traits.Studies have shown that 0.5%avermectin liquid fertilizer has the ability to knock down and kill root-knot nematodes.When diluted 800 times,the indicators of tomato agronomic traits reached the highest.Therefore,it is recommended to use 0.5%avermectin liquid fertilizer with a concentration of 800 times dilution,and the tomato has the best effect on root-knot nematode disease and growth.
