Embodiment 1

[0023] According to the method that every 100 parts of the spray aid contains 10-15 parts of the active ingredient carrier, 5-10 parts of glycerin, 15-30 parts of the surfactant, and the remaining amount is supplemented by vegetable oil, one kilogram of the spray aid is prepared.

[0024] In this example, different active ingredient carriers and surfactants were used for configuration, and the specific formulations are shown in Table 1.

[0025] Table 1:

[0026]

[0027] The preparation method of neonicotinoid pesticide insecticide comprises the following steps:

[0028] (1) At room temperature, mix the active ingredient of the insecticide with the carrier of the active ingredient at a weight ratio of 1:5~10,

[0029] (2) Mix the mixture obtained in step (1) into the surfactant solution, stirring constantly to prevent agglomeration,

[0030] (3) slowly drip glycerin into the mixed solution obtained in step (2) at a rate of 6 drops / s,

[0031] (4) Mix vegetable oil into ...

Embodiment 2

[0034] The No. 1-10 nicotine pesticide insecticide obtained in Example 1 was sprayed in the field by means of aerial spraying.

[0035] It was found that precipitation and nozzle blockage did not occur after repeated spraying, indicating that the auxiliary agent obtained in the present invention can effectively improve the solubility of insecticides and achieve low-capacity dissolution.

[0036] In order to further test the spray effect, we designed the aircraft spray contrast test. The "fog droplet test card" (manufactured by the Institute of Plant Protection, Chinese Academy of Agricultural Sciences) is used to detect the settlement and spreading of the liquid medicine. The spread of the liquid.

[0037] The solutions used for comparison were: the blank control containing only nicotine pesticides, the comparative example 1 with the addition of commercially available vegetable oil auxiliaries, and the comparison with the adjuvants disclosed in CN104488860B Example 1 and Exam...

Abstract

The invention belongs to the field of pesticides and particularly relates to a mechanized-control spraying assistant for a neonicotine pesticides. The mechanized-control spraying assistant is prepared from an active ingredient carrier, glycerine, vegetable oil and a surfactant; and per 100 parts of the spraying assistant comprises 10-15 parts of active ingredient carrier, 5-10 parts of glycerine, 15-30 parts of surfactant and the balance of vegetable oil, wherein the surfactant is a non-ionic or anionic surfactant, and the active ingredient carrier is composed of a starch carrier, a saccharide carrier and an inorganic carrier. Through an improvement on the assistant, the nicotine pesticide capable of being applied to aerial spraying is obtained; and the product is high in solubility and high in drift resistance and is applicable to low-gallonage spraying of aviation and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to the field of pesticide adjuvants, in particular to a mechanized control spray adjuvant for neonicotinoid pesticides and insecticides. Background technique [0002] Neonicotinoid insecticides mainly act on insect nerves, and have a nerve-blocking effect on the synaptic receptors of insect nerve axons. It has good systemic and osmotic effects, and has the characteristics of low toxicity, high efficiency, and long-lasting effect. This kind of insecticide is mainly used in crops such as fruit trees, and can control a variety of piercing and sucking mouthpart pests, such as gnat forests. [0003] In recent years, with the rise of aerial spraying, more and more planting areas and functions use aerial spraying. However, due to the small water consumption and high dilution concentration of aerial spraying, many traditional pesticide formulations cannot meet the requirements of aerial spraying....
