为了进一步明确96%金都尔和50%瑞飞特防除移栽油菜田杂草的效果以及对油菜的安全性,本站于1999～2000年度作了药效试验,现将结果报告如下: 试验设8个处理,3次重复,随机排列,每小区面积为56m~2,油菜移栽后4天施药,此时油菜已基本活棵。具体处理为:(1)96%金都尔EC50ml/亩;(2)96%金都尔EC60ml/亩;(3)96%金都尔EC70ml/亩;(4)50%瑞飞特EC60ml/亩;(5)50%瑞飞特EC80ml/亩;(6)50%瑞飞特EC100ml/亩;(7)50%乙单胺EC80ml/亩;(8)CK(喷清水)。 11月4日上午施药,亩用药量兑水50公斤。用背负式手动喷雾器进行全田喷雾。调查内容 (1)除草效果调查:药后30、60天各查一次禾本科杂草及阔叶杂草株数,2000年4月10日测杂草鲜重,最后分别
In order to further clarify the 96% Kindour and 50% Ruifute special effects of weed control transplanting rapeseed field and rapeseed safety, this site made a pharmacodynamic test in 1999 ~ 2000, the results are reported as follows: Test Set eight treatments, three repetitions, random arrangement, each plot area of 56m ~ 2, 4 days after transplanting rape pesticide application, this time rape has basically live tree. The specific treatment is as follows: (1) 96% Jindal EC50ml / mu; (2) 96% Jindal EC60ml / mu; (3) 96% Jindal EC70ml / Acre; (5) 50% Reefer EC80ml / mu; (6) 50% Reefer EC100ml / acre; (7) 50% B monoamine EC80ml / acre; The morning of November 4 spraying, mu amount of water watered 50 kg. Use the knapsack sprayer for field spray.
