Abstract

Disclosed is a fenfentrazone-atrazine compound dispersible oil suspension and a preparation method thereof, which relate to the technical field of annual weed control in cornfields. At least 2 parts fentrazone, 30 parts atrazine, 6 parts sodium methylene bis-naphthalene sulfonate, 2 parts xanthan gum, 2 parts ammonium lauryl sulfate, 15 parts emulsifier 602 and make up to 100 parts of methyl oleate. The raw materials are pumped into the preparation tank for mixing and stirring, and then firstly ground by a colloid mill, then finely ground by a sand mill, sampled and analyzed, filtered, measured, packaged, and put into storage after passing the test. The compounded dispersible oil suspension concentrate of fenmetrazone and atrazine at a ratio of 1:15 of 32% in the present invention can play an obvious synergistic effect, while the preparations mixed with other ratios, All can not reach the scope of obvious synergistic effect.

Description

technical field [0001] The invention relates to the technical field of preventing and controlling annual weeds in cornfields, in particular to a fenfentrazone-atrazine compound dispersible oil suspension and a preparation method thereof. Background technique [0002] At present, the existing herbicidal composition used for the control of annual weeds in cornfields, for example, the Chinese patent "CN104522031 A" discloses a "cornfield herbicide composition containing thionsulfuron-methyl", including the active ingredient fenfentrazone Ketone, thiazone-methyl and atrazine, wherein, fenflumezone accounts for 0.5% to 30% by weight of the composition, thiazone-methyl accounts for 0.5% to 30% by weight of the composition, and atrazine It accounts for 5%-80% by weight of the composition. In addition, the Chinese patent "CN 103053608 A" discloses a "weed herbicide", which is prepared according to the following weight ratio of raw materials: Amisofenac 9.5%, quizalofop-ethyl 2.5%, ...
