对称式喷头组合件在辣椒炭疽病防控中的应用评价

Application Evaluation of Symmetrical Sprinkler Assembly in Prevention and Control of Pepper Anthracnose

为验证对称式喷头组合件的应用效果,以辣椒炭疽病为防控对象开展防效和功效评价试验。试验以电动喷雾器通过多功能碳素喷杆连接对称式喷头组合件喷施药液,以常规喷头为对照,比较对称式喷头组合件与常规喷头施药对辣椒炭疽病的防控效果及省时省药液功效。结果表明,喷施25%溴菌腈EC50 mL/667m^(2)后7 d,对称式喷头组合件施药的平均防效比常规喷头高4.90%~8.90%,差异显著;对称式喷头组合件与常规喷头喷雾作业相比,平均可节约喷药时间55.51%,节约药液用量67.99%。该结果充分证明,使用对称式喷头组合件施药较常规喷头施药防控辣椒炭疽病省时、省药且防效好。

The control effect and efficacy evaluation test of Pepper anthracnose were carried outin order to verify the application effect of symmetrical sprinkler assembly.In this experiment,electric sprayer was connected with symmetrical sprinkler assembly through multifunctional carbon spray bar,and conventional sprinkler was used as control to compare the prevention and control effects of the two on Pepper anthracnose and the time-saving effect of the liquid medicine.The results showed that after 7 days of spraying 25%bromothalonil EC 50 mL/667 m^(2),the average control effect of symmetrical sprinkler assembly was 4.90%~8.90%higher than that of the conventional sprinkler,witha significantdifference.As compared to the conventional sprinkler,the symmetrical sprinkler assembly could save 55.51%of spraying time and 67.99%of liquid pesticide consumption.The results fully demonstrate thatthe application of the symmetrical sprinkler assembly ismoretime-saving,pesticide-saving and labor-saving compared with conventional sprinklerto prevent and control Pepper anthracnose.
