摘要
通过田间试验研究了10%世高水分散粒剂6 000倍液对辣椒白粉病Leveillula taurica的防治效果。结果表明,10%世高水分散粒剂6 000倍液对辣椒白粉病的防治效果好,第1次施用10%世高水分散粒剂6 000倍液后,重复区Ⅰ、Ⅱ、Ⅲ的防治效果分别为96.95%、95.99%、96.11%;第2次施药后重复区Ⅰ、Ⅱ、Ⅲ的防治效果分别为99.49%、98.10%、99.01%。显著优于45%晶体石硫合剂300倍液(第1次施药后,重复区Ⅰ、Ⅱ、Ⅲ的防治效果分别为59.64%、42.59%、67.62%;第2次施药后,重复区Ⅰ、Ⅱ、Ⅲ的防治效果分别为76.60%、70.94%、81.04%)。说明10%世高水分散粒剂6 000倍液是防治辣椒白粉病的理想药剂。
Control effects of 10% Difenoconazole on Leveillula taurica in pepper were studied in field experiement to be contrasted with 45% Lime sulfur(ESA). After the first application of 10% Difeneconazole at a dilution of 1:6 000, control effects on Leveillula taurica in pepper in three replicate fields were 96. 95% ,95.99% ,96, 11% respectively;And after the second application of it,the effects in the three fields improved to 99. 49% ,98. 10% ,99.01%. After the first application of the 45% Lime sulfur (ESA) at a dilution of 1 : 300, control effects in three replicate fields only were 59. 64% ,42. 59% ,67.62% respectively; And after the second application of it, the effects were 76. 60% , 70. 94% , 81.04%. The experiment shows that the 10% Difenoconazole is the ideal fungicide in controlling the Leveillula taurica of pepper.
