摘要
[目的]明确根施阿米西达对番茄叶霉病的防治效果、持效期及对番茄生产的影响.[方法]采用田间试验研究4个根施阿米西达达处理、1个喷施阿米西达对照和1个清水对照对番茄叶霉病的防治效果及对番茄生长的影响.[结果]根施阿米西达超过1 500ml/hm2,药后75 d对叶霉病的防治效果均超过90％,喷施阿米西达对照的防治效果仅为22.24％,相同用药量持效期较喷雾防治至少高出20d.阿米西达对番茄植株表现出低浓度促进生长而高浓度抑制生长的特性.[结论]综合考虑,建议春茬番茄(8.10万株/hm2)根施阿米西达1 500 ml/hm2预防番茄叶霉病.
Abstract
[Objective] To explore the control efficiency of root application of amistar to tomato leaf mould and tomato growth.[Method] Field experiment was carried out four amistar treatments,one amistar spraying control,and one clean water control.[Result] Root application of more than 1500 mL/hm2,control efficiency of leaf mold on the 75th day was higher than 90％;the control efficiency of spraying control was only 22.24％.The lasting period of the same dosage was 20 days greater than spraying control.Besides,amistar concentration at low concentration promoted the growth;while that at high concentration inhibited the growth.[Conclusion] 1 500 mL/hm2 amistar should be applied in root of spring tomato (81.0 thousand/hm2) to prevent tomato leaf mould.
