Abstract
The imidacloprid new dosage form pesticide for controlling sucking insect pests of aphid and fulgorid, etc. with sucking mouth parts is made up by using (wt%) 1-15% of imidacloprid, 4-35% of emulsifying agent, 0.1-0.2% of synergistic agent and 5-30% of cosolvent and water, and possesses the features of high-efficiency, low-toxin, small dose, quick-killing insect pests and long effective period, and can be used to completely substitute existent imidacloprid water-dispersible powder.
Description
The present invention relates to a kind ofly anti-to eliminate aphis, the imidacloprid micro emulsion insecticide of sucking pest such as plant hopper, the water base micro emulsion insecticide of a kind of efficient, low toxicity that processes by O/W microemulsion manufacturing process such as the former powder of Imidacloprid, emulsifier, synergist, cosolvent, water of saying so in more detail.
At present, the sucking pest such as aphid, aleyrodid, plant hopper, thrips, scale insect that is used for crops such as fruit tree, wheat, paddy rice, peanut, cotton, vegetables is more effectively pounced on lice aphid pulvis, is pounced on lice aphid missible oil, control efficiency is good, but cost is too high, and drift is big during use, permeability is relatively poor.
The objective of the invention is to overcome the deficiency of above-mentioned existing procucts, and provide that the former dose of a kind of usefulness is few, with low cost, drift is little, permeability is strong during dispenser micro emulsion insecticide.
Purpose of the present invention can realize by following measure:
In reactor, add successively:
(a) weight concentration is the Imidacloprid of 1-15%;
(b) weight concentration is the emulsifier of 4-35%;
(c) weight concentration is the cosolvent of 5-30%;
(d) weight concentration is the synergist of 0.1-2%;
The rest is water or deionized water.
Purpose of the present invention can also realize by following measure:
(have another name called: Imidacloprid) former powder and part cosolvent add in the reactor successively pouncing on the lice aphid, be heated to 80-100 ℃, stir the 5-10 branch, drip emulsifier then, in 10-30 minute, add, temperature remains on 90-100 ℃, mixing speed 200-400 rev/min, under heat-retaining condition, add hot water (temperature 95-100 ℃) then, in dividing, 10-40 adds, add surplus cosolvent and synergist again, stirred 5 minutes, and be cooled to about 30 ℃ with cold water, this moment, emulsion transferred microemulsion to, filter, packing promptly gets agricultural chemicals of the present invention.
Its molecular structure of the Imidacloprid that uses among the present invention is:
Imidacloprid can the 3-picoline be a raw material, and itself and chlorobenzoyl chloride reaction are made 2-chloro-5-picoline (chloropyridine), and logical again chlorine makes 2-chloro-5-chloromethylpyridine (dichloropyridine).With its again with N-nitro-4, the reaction of 5-dihydro-1H-imidazoles-2-amine (imidazolidine) makes Imidacloprid." imidazoles " then can be produced by ethylenediamine and nitroguanidine reaction.Process chart is seen Figure of description 1.
Used emulsifier is according to 1: 1 composite forming by anion surfactant and non-ionic surface active agent among the present invention.
Used cosolvent is by composite forming such as higher aliphatic, PVP, ether, polyalcohols among the present invention, has height and oozes, helps emulsification function and can antifreeze, froth breaking, increases the stability of system simultaneously.
Used synergist is Butacide, Octacide 264 etc. among the present invention.
The present invention give further instruction in order to illustrate better below by embodiment:
