通过1963年的研究表明,1:800倍46.6%E 605液在田间喷药后5天采制成的干茶中残留量为4—4.57 p.p.m,10天后为1.94—2.45 p.p.m,其残留药量分别为原喷药量的2%和1%左右,冬季喷药春季4月采制成的干茶中残留量为1.3—1.5 p.p.m,因此在生产条件下建议将浓度降至1000倍以下,并限于在冬季使用。1:300倍50%1059液在田间喷
According to the 1963 study, 1: 800 times 46.6% of E 605 liquid was 4-4.57 ppm in dry tea made from 5 days after spraying in the field and 1.94-2.45 ppm after 10 days. The residual dose Respectively, the original amount of spray 2% and 1%, winter spraying spring April harvest made of dried tea in the residual amount of 1.3-1.5 ppm, it is recommended in the production conditions to reduce the concentration to 1000 times the following, and Limited to use in winter. 1: 300 times 50% 1059 liquid spray in the field
