Problems solved by technology

[0005] For example, organosilicon, a pesticide synergist that has been widely promoted in the past few years, is a polysiloxane surfactant, which is characterized by reducing surface tension and improving wetting and spreading, but it is unstable to acid and alkali and moisture It will also decompose when it is high, and because of its high price, good and bad people are mixed, which poses a certain risk to farmers' use

Embodiment 1

[0027] Embodiment 1. Preparation of pesticide synergist

[0028] (1)

[0029]

[0030] Preparation method: Accurately weigh styrylphenyl polyoxyethylene ether, calcium dodecylbenzenesulfonate, butylated hydroxyanisole, and methyl oleate according to the formula ratio, put them into a stirring tank, and stir at a speed of 1000rpm. The stirring time is 60 minutes, and after all the materials are mixed evenly, the pesticide synergist is obtained.

[0031] (2)

[0032]

[0033] Preparation method: Accurately weigh styrylphenyl polyoxyethylene ether, the addition condensate of castor oil and ethylene oxide, benzotriazole, and biodiesel according to the formula ratio, put them into a stirring tank, and stir at a speed of 1000rpm, stirring time 60min, after all the materials are mixed evenly, the pesticide synergist is obtained.

[0036] Preparation method: Accurately weigh fatty alcohol polyoxyethylene ether, fatty acid sorbitan, polysorbate, and m...

Embodiment 2

[0037] Embodiment 2. Field application examples

[0038] (1) Application example of synergist: comparative test for herbicide 15% mesotrione suspension concentrate and 38% atrazine suspension concentrate synergist

[0039] Adopt the greenhouse potting method, each pot area is 200cm2, sow the barnyardgrass or retroverted amaranthus seeds that have been germinated and dewy, the soil is loamy soil, and placed in the greenhouse for cultivation. The temperature in the greenhouse is 28°C to 5°C during the day, and 23°C to 5°C at night. ℃; relative humidity is 75% ± 5%. Treat the weeds at the 3-4 leaf stage. The seedlings were thinned one day before spraying, and 10 weeds were kept in each pot, sprayed with a Potter nozzle, the spray volume was 450kg / hm2, and the control was sprayed with clear water. Each treatment was repeated 4 times, and the experiment was repeated 4 times. Investigate the control effect within a certain period of time after the treatment, weigh the fresh weight...

Abstract

The invention discloses a pesticide synergist and a preparation method and belongs to the technical field of pesticide. The pesticide synergist serving as a pesticide auxiliary and a synergist can be directly added during production of pesticide preparations, and can be sprayed before field atomizing of peasant households and after being mixed uniformly in a pesticide preparation product bucket. The pesticide synergist can be used as a functional auxiliary during processing of the pesticide preparations and can server as the pesticide synergist to lower surface tension, so that pesticide efficacy is improved. The pesticide synergist is suitable for all pesticide products and can be popularized and applied in pesticide preparation processing enterprises and peasant households.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide synergist with stable properties and strong compatibility and a preparation method thereof formulated by using the properties of fatty acid methyl esters. Background technique [0002] Pesticides are used to prevent, eliminate or control diseases, insects, weeds and other harmful organisms that endanger agriculture and forestry, as well as to regulate, control and affect the metabolism, growth, development and reproduction of plants and harmful organisms. A substance or a mixture of several substances and its preparations produced by biological and other natural products and applied biotechnology are indispensable products in food crops, melon, fruit and vegetable cultivation, and forestry. [0003] Most pesticides are insoluble in water and cannot be used directly. They need to be processed into suitable dosage forms with various auxiliaries to exert their efficac...
