Embodiment 1

[0032] Mix 60 grams of paraffin oil and 20 grams of Synperonic A14 (fatty alcohol polyoxyethylene ether) evenly, dissolve 2 grams of KOH in 18 grams of ammonia water, and then pass the mixture of paraffin oil and fatty alcohol polyoxyethylene ether through Fluko-F25 high-speed The adjuvant product for herbicides is obtained after thorough mixing with an emulsifying shearing machine.

Embodiment 2

[0034] 57 grams of methylated rapeseed oil prepared by reacting rapeseed oil with NaOH and methanol, adding 10 grams of ammonium sulfate aqueous solution, 15 grams of ammonia water and 18 grams of SynperonicA14 (fatty alcohol polyoxyethylene ether), high-speed emulsification by Fluko-F25 The shearing machine stirs at a high speed to dissolve and mix the ingredients to obtain the adjuvant product for herbicides.

Embodiment 3

[0036] 60 grams of soybean oil, 23 grams of ammonium sulfate aqueous solution, 2 grams of KOH and 15 grams of octylphenol polyoxyethylene ether were stirred and mixed, and emulsified by a Fluko-F25 high-speed emulsifying shear to form a uniform and transparent herbicide Use auxiliary products.

Abstract

The herbicide assistant of the present invention is one kind of transparent liquid product prepared with mineral and / or vegetable oil, esterified or un-esterified, as main material, pH regulator, liquid or solid fertilizer, surfactant, etc in certain weight proportion and through mixing. The herbicide assistant is used as the synergist added into the herbicide during producing herbicide or before spraying herbicide. The herbicide assistant can raise the effect of herbicide, increase the deposition, spreading and absorption of herbicide in leaf, lower herbicide consumption and use cost and reduce environmental pollution caused by herbicide.

Description

field of invention [0001] The invention relates to an adjuvant for pesticides and an application method thereof, in particular to an adjuvant for herbicides and an application method thereof. Background technique [0002] General herbicides for post-emergence treatment are processed into wettable powders, emulsifiable concentrates, emulsions in water, suspension concentrates or water-dispersible granules, etc., which are diluted with water and then sprayed. Many additives and auxiliaries can increase the efficacy of herbicides and reduce the amount of herbicides used. For example, the application of ammonium sulfate, urea, Yaoxiaobao, Quard7, Scoil, etc. can improve the application effect of herbicides to varying degrees by promoting herbicide absorption or spreading on the leaf surface. However, the effect of herbicides is closely related to environmental conditions, spraying methods, spray volume, and the deposition, distribution, penetration, and absorption of spray drop...
