Abstract
An emulsified oil as pesticide is prepared from built-up chlorfluazuron and phoxime in weight ratio of 1 : (10-25) and the ratio of chlorfluazuron-phoxime mixture in the pesticide is 40-45%. Its advantages include high cotoxicating coefficient (CTC) greater than 100, low poison, broad spectrum, low dosage, high activity to kill pests and quickly taking its effect.
Description
What the present invention relates to is agricultural chemical insecticide, particularly by organic phosphor and benzoyl urea agricultural chemicals through the composite preparation that forms.
For agricultural production, agricultural chemicals is indispensable, yet pesticide species is dangerous to people and non-target biology owing to the big residence time length of toxicity, use the back that ecology and environment are had harm, use the biological reasons such as some defective is arranged in resistance and the use that produce of target repeatedly in a large number, constantly needs to update.Insecticide particularly, this problem is particularly serious, will stop using too by force because of toxicity as the insecticide methamidophos of present China consumption maximum.
At the problem that insecticide exists at present, the present invention is intended to be re-dubbed with existing pesticide species the insecticide variety of better insecticidal effect.
Phoxim (Phoxim, also the name Phoxim, phoxim, phoxim)
Having stomach toxicity and action of contace poison, is a kind of low toxicity broad-spectrum organophosphorous pesticide, yet plant does not have systemic action and see that light easily decomposes to it, thereby the longevity of residure is too short.
Fluorine bell urea (Hexaflumuron, code name are XRD-473)
Be a kind of process for preparation of benzoylurea compounds, have very high desinsection and contact ovicidal activity that its effect is to suppress the insect decortication and kill it, can also suppress the insect eating speed simultaneously, its insecticidal spectrum is wide, toxicity is low.But the quick-acting difference is the big shortcoming of one.
The present invention carries out two kinds of dissimilar agricultural chemicals composite and reaches mutually the purpose of covering the shortage, increase effect.Fluorine bell urea is an insect growth regulator, IGR, main effect is to disturb the insect epidermal growth, the mechanism of action that swashs the acetylcholinesterase in the property conduction with the inhibition choline of phoxim is different, meets the principle of complex preparation, and the two is used with certain proportion has obvious synergistic effect.This conclusion is confirmed with following experiment: be the mixture determining lethality of target insect with the phoxim of fluorine bell urea and different proportion with the cotton bollworm, with the LC of Polo calculating
50Calculate CTC (co-toxicity coefficient) value with proportioning, draw table 1, table 2.The CTC value is an antagonism less than 100, and greater than 100 for synergistic effect, about 100 is summation action.

0.9524 two kinds of mixed pesticides are at fluorine bell urea as seen from the above table: phoxim=1: 10～20 o'clock its CTC value is all greater than 100.
Therefore technical scheme of the present invention is: in the weight ratio of fluorine bell urea and phoxim is that 1: 10～25 ratio is mixed with mixture, is good with 1: 19～20.This mixture is added solvent, emulsifier, and auxiliary elements such as spreader-sticker are mixed with the missible oil of fluorine-containing bell urea and phoxim 40～45%.Missible oil is brown or the purple homogeneous liquid, water content≤0.5%, and acidity is (with H
2SO
4Meter)≤0.4%.It is very remarkable to convert water control farmland insect pest effect with this missible oil.
Suffering of the present invention (sulphur phosphorus)-fluorine (bell urea) compound agricultural insecticide, its prescription rationally, the CTC value is significantly greater than 100, its toxicity is low, rush out that spectrum is wide, consumption is few, to insect knock down speed fast, very high desinsection is arranged and contacts ovicidal activity, remedy the slow deficiency of fluorine bell urea speed of action, make phoxim obtain new life again, than single separately with obvious synergistic effect has been arranged at present.
Example
The preparation of the hot missible oil of 42% fluoro-.
The former medicine 6.2kg of fluorine bell urea, the purity of getting purity 98% is that 85% phoxim 141kg under agitation adds assistant agent 153kg such as solvent, emulsifier in the preparation still, and mixing gets the 297.5kg product after filtering.Wherein contain phoxim 40.65, fluorine-containing bell urea 2.03%, moisture content 0.22%, acidity is (with H
2SO
4Meter) 0.16%, emulsion stability is good.
At new city subarea, Shenyang City rural area 840m
