安徽省徽州地区植保站 近年来,不少地方都在试用3个1(1背包水、1毫米孔径喷片、喷1亩田)小容量和低容量喷雾技术防治水稻等多种作物害虫,其防效不亚于常规喷雾,但该法用于防治农作物病害,是否也能取得常规喷雾法同样的效益,所见报道不多。为此我们1984年在水稻上进行了防治稻穗瘟的试验。 供试药械 工农16型背负喷雾器;孔径1.3毫米铜喷片;1.0毫米钢玉瓷喷片;0.7毫米不锈钢喷片。均系第一次使用。 试验药剂:30％三环唑胶悬剂(上海农
Plant Protection Station in Huizhou, Anhui Province In recent years, many small-volume and low-volume spray technologies are being used to control many crop pests such as rice in 1 (1 backpack water, 1 mm aperture jet and 1 mu sprayed field) in many places. As effective as conventional spray control, but the law is used to prevent crop diseases, can also get the same benefits of conventional spray method, seen little. To this end, we conducted a test on rice in 1984 to control rice blast. For test kit workers and peasants 16-type backpack sprayer; aperture 1.3 mm copper spurt; 1.0 mm steel jade porcelain spray; 0.7 mm stainless steel spray tablets. Are the first time use. Test drugs: 30% tricyclazole suspension (Shanghai Agricultural
