Abstract

The invention relates to the field of pesticide formulations and discloses a dispersible thiamethoxam oil suspension. The thiamethoxam oil suspension comprises the following raw materials in percentage by weight: 1-25% of thiamethoxam, 5-25% of a surfactant, 0.1-10% of a functional additive and 50-94% of one or combination of two of plant oil or mineral oil and ester thereof. The thiamethoxam oil suspension mainly has the advantages as follows: (1) a synergistic effect is achieved as the mineral oil or the plant oil has a remarkable synergistic effect for prevention and control of pesticides on pest and disease damage; (2) the pollution degree is low as the raw materials used in the suspension are all non-destructive and lowly-destructive to the environment; (3) the plant resistance is improved as the plant growth is improved while the pest damage is prevented and controlled after the suspension is applied; (4) the hidden trouble in stability of the suspension is improved.

Description

A kind of Diacloden oil suspending agent
Technical field
The present invention relates to formulations of pesticide field, but particularly Diacloden dispersed oil suspending agent.
Background technology
Diacloden, its mechanism of action is similar to Imidacloprid, alternative inhibition insect central nervous system nicotinic acid nAChR ligands, and then the normal conduction of blocking-up insect central nervous system, death while causing insect the paralysis machine to occur.Not only have tag, stomach toxicity, systemic activity, and there is higher activity, better safety, wider insecticidal spectrum and the characteristics such as speed of action is fast, the lasting period is long, be the better kind that replaces those are high to mammalian toxicity, residual and environmental problem are arranged organic phosphor, carbamate, organochlorine insecticides.To coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, can effectively prevent and treat the insect that the insect such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and knot polytype chemical pesticide produce resistance.With Imidacloprid, Acetamiprid, Nitenpyram without cross resistance.Both can be used for cauline leaf processing, seed treatment, also can be used for soil treatment.Suitable crop is rice class crop, beet, rape, potato, cotton, Kidney bean, fruit tree, peanut, sunflower, soybean, tobacco and citrus etc.Under recommended dose, use to crop safety, without poisoning.
The formulation that Diacloden is used as insecticide at present mainly contains suspending agent, water dispersible granules.The present invention has solved the livering problem with respect to suspending agent, with respect to water dispersible granules, has reduced production cost, and different synergistic effects is all arranged.
