Abstract
The present invention relates to one kind of recompounded pesticide containing clam worm toxin and organic heterocyclic compound. It includes bitertanol or monuron or their mixture as well as Bichonglin. During the recompounding, Imidan is first dissolved in surfactant containing polar organic solvent, bitertanol or monuron or their mixture and water are then added under stirring and the mixture liquid is heated to 40-50 deg.c and maintained for 30 min to reach the pH value of 5.5-7.5. The pesticide has effective and relatively lasting preventing and killing effect to rice hopper, rice leaf rolling borer, yellow rice borer and other rice pests.
Description
The present invention relates to a kind of neires toxin and composite insecticide that forms of organic heterocyclic molecule of containing, particularly a kind of insecticide and preparation method that contains dimehypo (or desinsection list, or the two mixture) and Imidacloprid.
At present, the insecticide that is used to prevent and treat rice grub in the agricultural production is a lot, mainly contain organophosphorous pesticide or their compounds such as acephatemet, isocarbophos, dichlorvos, phoxim, it is longer that these agricultural chemicals are used to prevent and treat time of rice grub, insect produces stronger pesticide resistance to these agricultural chemicals, control efficiency is relatively poor, and wherein some agricultural chemicals such as toxicity such as acephatemet, isocarbophos are higher, easily cause person poultry poisoning's accident.Chinese patent application numbers 96111466.5 and 94103883.1 discloses the Recompounded pesticide that contains dimehypo (or desinsection list, or the two mixture), but its insecticidal effect to some rice grub (as water rice hopper) is not remarkable.Chinese patent application 96191646.X discloses a kind of pesticide imidacloprid compound, to killing water rice hopper remarkable result is arranged, but the effect of the control snout moth's larva of rice is very poor.As seen, Imidacloprid or dimehypo use control during rice grub separately, and often repeatedly medication is taken a lot of work and mistake farming season.Test finds that two kinds of agricultural chemicals of dimehypo and Imidacloprid are shared, and obvious synergistic effect is arranged.But these two kinds of medicines are difficult to evenly be mixed in the field temporarily, or simply use back control efficiency instability with.
The purpose of this invention is to provide a kind of drug effect height, the insecticide that can prevent and treat multiple rice grubs such as water rice hopper, rice leaf roller, paddy stem borer that the property of medicine is stable.
Insecticide of the present invention is made up of dimehypo (or desinsection list, or the two mixture), Imidacloprid, surfactant, polar organic solvent and water.
The percentage by weight of each component is dimehypo (or desinsection list, or the two mixture) 10-20, Imidacloprid 0.1-1.5, surfactant 8-15, polar organic solvent 10-20 and water 53-68.
Surfactant of the present invention is YZ-905, farming breast 0204, OP-10, neopelex.Polar organic solvent is ethanol, isopropyl alcohol, acetone, dimethyl formamide, N-Methyl pyrrolidone.
Insecticide compound method of the present invention is: earlier Imidacloprid is dissolved in the polar organic solvent that contains surfactant, under agitation add dimehypo (or desinsection list slowly, or the two mixture), heat to 40-50 ℃, kept 30 minutes, regulate the pH of mixed value with the 10mol/L NaOH aqueous solution or 3.5mol/L aqueous sulfuric acid, it is reached till the 5.5-7.5.
Imidacloprid (Imidacloprid) has another name called Imidacloprid, sweeps only, and miaow amine, chemical name are 1-(6-chloro-3-pyridylmethyl)-N-Nitroimidazoline-2-imines.
Dimehypo is a kind nereistoxin pesticide, and its chemical name is a 2-dimethylamino-1, the 3-dual-propane sodium thiosulfate; The chemical name of desinsection list is 2-dimethylamino-1-thiosulfuric acid-3-sodium thiosulfate base propane.
Insecticide of the present invention is a kind of low toxicity type insecticide, based on stomach toxicity, tag, inhales and ovicidal action in having concurrently.Preparation method has solved being mixed of hydrophily agricultural insecticide two (or desinsection list, or the two mixture) and non-hydrophily pesticide imidacloprid, and does not influence the stability of two kinds of agricultural chemicals.Obvious synergistic effect is arranged after composite, and Toxicity Determination the results are shown in Table 1.As can be seen from Table 1, both compounds have obvious synergistic effect to water rice hopper, and co-toxicity coefficient reaches
The co-toxicity of table 1 dimehypo and the different proportionings of Imidacloprid
200-600, synergy multiple reach 1-5 doubly, thereby have reduced the agricultural chemicals using dosage, have reduced cost.Especially the present invention has selected suitable surfactant and solvent for use, has strengthened soup greatly and has puted forth effort and infiltration capacity in the exhibition of target, maintains desinsection effectiveness preferably in a long time.Because the insecticidal mechanism difference of two kinds of agricultural chemicals among the present invention, therefore the insecticidal effect of multiple rice grub that organophosphorous pesticide is developed immunity to drugs such as water rice hopper, rice leaf roller, paddy stem borer etc. all has good control efficiency, sees Table 2, table 3, table 4.Prove that through skin and oral toxicity animal experiment insecticide of the present invention belongs to low-toxin farm chemicals.
