Problems solved by technology

[0004] The pear psyllid belongs to the family Psyllidaceae of the order Homoptera, and is a common pest of pear trees. The pear psyllid directly damages the buds, leaves, twigs, and flower buds by stinging and sucking the buds, leaves, twigs, and flower buds. The nymphs secrete mucus, attracting aphids and coal pollution bacteria. The leaves cause indirect damage, brown spots appear and cause early leaf fall, and at the same time pollute the fruit, seriously affecting the yield and quality of pears, and the mucus secreted by pear psyllids can wrap the worms, and the liquid cannot penetrate into the worms, so it cannot be killed. Pear psyllid, making pear psyllid extremely difficult to control

Embodiment 1

[0024] Spinosad 2.0%, perfluoroalkyl polyoxyethylene ether 3.0%, nonylphenol polyoxyethylene ether phosphate 3.0%, EO-PO block polymer 2.0%, silicone defoamer 0.3%, silicic acid Magnesium aluminum 1.0%, xanthan gum 0.3%, ethylene glycol 4.0%, deionized water to make up to 100%.

[0025] The preparation process is as follows: According to the formula requirements, using water as the medium, mix the active ingredients, synergists, emulsifiers, defoamers, thickeners, antifreeze and other components according to the proportion of the formula to obtain an aqueous suspension, 25 Under the condition of ℃±5℃, the obtained aqueous suspension was ground by a sand mill for 60 minutes, and then put into a shearing machine and cut for 10 minutes to prepare a spinosad suspension.

Embodiment 2

[0027] Spinosad 15.0%, perfluoroalkyl polyoxyethylene ether 3.0%, nonylphenol polyoxyethylene ether phosphate 3.0%, EO-PO block polymer 2.0%, silicone defoamer 0.3%, silicic acid Magnesium aluminum 1.0%, xanthan gum 0.3%, ethylene glycol 4.0%, deionized water to make up to 100%.

[0028] The preparation process is the same as in Example 1.

Abstract

The invention relates to a synergistic spinosad suspending agent, and belongs to the technical field of pesticide suspending agents, wherein the active components of the suspending agent comprise spinosad and a synergist, and the total mass of the spinosad and the synergist is 5-25% of the total mass of the suspending agent. According to the invention, perfluoroalkyl polyoxyethylene ether and spinosad are compounded, so that the acting effect of spinosad for preventing and treating piercing-sucking pest psylla chinensis can be effectively improved, the permeability is enhanced, mucus secreted by psylla chinensis can be quickly cracked, liquid medicine can be fully contacted with insect bodies, the effects of quick dissolution and quick insect killing are achieved, and the quick-acting property of the agent is improved; and the spinosad and the preparation thereof are easy to decompose under the illumination condition, the perfluoroalkyl polyoxyethylene ether and the spinosad are compounded to prepare the suspending agent, the photolysis resisting effect can be achieved, the stability of the agent is improved, and the lasting period of the agent in use is prolonged.

Description

technical field [0001] The invention relates to a synergistic spinosad suspension concentrate, which belongs to the technical field of pesticide suspension concentrates. Background technique [0002] Spinosad is a macrolide biopesticide, which has quick contact and stomach poisoning effects on pests, but no systemic effect; it has a long residual effect period, and has certain ovicidal effect on some pests, which can effectively control Pests include pests of Lepidoptera, Diptera and Thysanoptera, and certain specific types of pests of Coleoptera, Orthoptera, Hymenoptera, Isoptera, Fleas, Dermatoptera and Rodentia. poisonous effect, and the insecticide has the advantages of long duration and low residue. However, spinosyn will be decomposed into inactive compounds under the action of light conditions, and it is easily degraded by light factors during storage, transportation and use. [0003] Fluorocarbon surfactants are widely used in synthetic detergents, cosmetics, food,...
