花生锈病是一种发展迅速,危害严重的病害。1970年只在我县局部地区发生,1973年大面积流行,全县93000亩春花生有8000亩发病,使春花生大面积减产。为了防治花生锈病,今年我们在高州农校进行药剂防治试验。试验共分两部分: 1.花生不同生育期喷药防治锈病试验。为了掌握喷药适期和喷药次数,我们在同一丘田,分别于春花生盛花期,盛针期和结荚期进行喷药,每次每亩喷1:1:100波尔多液100斤。试验结果:以盛花期、盛针期和结荚期各
Peanut rust is a rapidly developing and devastating disease. In 1970 only in some areas of our county, large-scale epidemic in 1973, the county 93000 acres of spring peanut disease incidence of 8000 acres, so that large areas of peanut yield reduction. In order to prevent peanut rust, this year we were in the high school of pesticide control experiments. Test is divided into two parts: 1. peanut spraying different stages of development of rust prevention and control test. In order to grasp the spraying period and the number of spraying, we were in the same hilly fields, respectively, in the flowering of spring peanut Sheng period and pod stage spraying, each spray 1: 1: 100 Bordeaux mixture of 100 pounds. Test results: To flowering period, Sheng pin and pod stage
