Problems solved by technology

Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment.

Abstract

The invention discloses a profenofos.phoxim emulsifiable concentrate and its preparation method. The profenofos.phoxim emulsifiable concentrate comprises (by wt%) profenofos 4, phoxim 36, calcium dodecylbenzene sulfonate 7, pesticide emulsifier 600# 8, safener 10, and xylene 35. The preparation method includes mixing phoxim and fillers according to certain proportions into profenofos.phoxim compound. The profenofos.phoxim emulsifiable concentrate has delayed crop resistance, improved control effect of the pesticide, reduced cost, saved labor, and improved economic benefit; and it is used in mulberry with registration by the State Department of Agriculture.

Description

technical field [0001] The invention relates to a compound pesticide, in particular to a probromide·phoxim emulsifiable concentrate and a preparation method thereof. Background technique [0002] According to the principle of one drug with multiple treatments, the pesticides formulated by the compound preparation method according to a certain mixing ratio are called compound pesticides. Traditional pesticides are single-dose, single-dose effect is single, and long-term use leads to continuous improvement of crop resistance, which has a serious impact on the effect of pesticides. Farmers often use increased dosage to maintain the effect, which increases the cost of use and causes damage to the environment. . Probromide·phoxim EC is registered for use on mulberry trees. It is currently one of the few varieties that have been registered by the Ministry of Agriculture in China and used on mulberry trees. Contents of the invention [0003] Purpose of the invention: the pu...
