| 摘 要： | 68％金雷多米尔-锰锌WG是辣椒疫病较为理想的防治药剂。于辣椒疫病发病前或初期极少数病株出现开始施药,施药次数以施药三次为宜,每次施药间隔期为7～10d(视气候条件和发病情况而定),使用剂量为100g～120g/667m2(a.i.为1020g/hm2)。每667m2喷施药液60kg时,其对辣椒疫病的防效为80.38％～85.44％,辣椒增产率为17.76％～27.12％。施药方法采用常规喷雾法,将药液均匀喷施于辣椒植株靠近地面的茎基部。

| Abstract: | Phytophthora capsici is a serious pathogen causing large loss of the chilli yield. Our experiment results showed that 68% Gold - radomil is a better fungicide to control the disease. Its control effect reached 80. 38%~85. 54% and made pepper yield increase by 17. 76%~27. 12%, when the application rate was 100g~120g/667m2(a. i. 1020g~1224g/ha) and water dispersing agent rate 60 kg/667m2,by 3 sprayings at intervals of 7~10d . Gold -radomil may be a candidate product to control Phytophthora capsici for mancazob and copper - sulfur and some other fungicides. |
