Description
Technical field
The present invention relates to a kind of control rice grub composition pesticide, compound pesticide composition of particularly fluorine-containing worm nitrile and Rogor and preparation method thereof.
Background technology
In recent years, because a large amount of uses of various agricultural chemicals cause the pest pesticide resistance more and more higher, be China's insect pest of rice as water rice hopper, striped rice borer, paddy stem borer, rice leaf roller, take place particularly serious in Yangtze river basin rice district.Can cause a large amount of withered hearts in tillering stage, except that causing dead ears, also cause a large amount of insect bite strains, make its lodging in blocks at late growth stage of rice.In chemical agent control, the main at present pesticide species that uses as: clam worm property agricultural chemicals such as desinsection list, dimehypo have produced very strong pesticide resistance, agricultural chemicals such as Hostathion of Shi Yonging in succession, pesticide resistance is obviously rising also.The good agricultural chemicals of control efficiency has kinds such as fluorine worm nitrile, happiness at present, but because the price height, quick-acting is poor slightly, and certain limitation is in use arranged.
Fluorine worm nitrile (Fipronil) is a kind of Phenylpyrazole insecticides, it is again effective blocking agent of the chloride channel of r-aminobutyric acid adjusting, therefore and the normal effect of interference insect central nervous system, insecticidal spectrum is wide, various insects such as Homoptera, orthoptera, Semiptera, thrips and coleoptera are had stomach toxicity, action of contace poison, and certain systemic function is arranged.Fluorine worm nitrile is widely used in rice grub in recent years, and rice grub is had the better prevention effect, and still, fluorine worm nitrile is to the toxicity height of fishes and shrimps, in the network of rivers, the lake country uses and be subjected to certain limitation.The quick-acting of fluorine worm nitrile is relatively poor simultaneously, and price is higher.
Rogor wide spectrum Nankor has and tags and stomach poison function, by suppressing the acetylcholinesterase in the insect bodies, hinders nerve conduction and causes death, quick-acting is better, and cost is lower, and the lasting period is short partially, Rogor is low to higher mammal toxicity, and is lower to aquatile toxicity
Summary of the invention
Purpose of the present invention is exactly for overcoming the deficiency that above-mentioned use agricultural chemicals exists, a kind of fluorine-containing worm nitrile and Rogor compound pesticide composition and preparation method thereof are provided, fluorine-containing worm nitrile and Rogor compound pesticide composition, it had both kept the desinsection wide spectrum and the advantage good to the control efficiency of insect of fluorine worm nitrile, the quick-acting that keeps Rogor, can overcome the shortcoming that fluorine worm nitrile exists again, reduction is to other biological toxicity, strengthen quick-acting, prolong the lasting period, enlarge insecticidal spectrum, reduce cost, adapt to the requirement of China, and prepare easy to use, safe control rice grub agricultural chemicals.
The object of the present invention is achieved like this, the compound pesticide composition of a kind of fluorine-containing worm nitrile and Rogor, it is characterized in that containing active ingredient fluorine worm nitrile and Rogor, gross weight with composition is a benchmark, fluorine worm nitrile content is 0.5～4%, Rogor content is 20～40%, additive level is 56～79.5%, described additive is solvent and emulsifier and antifreeze, solvent is one or more in dimethylbenzene or toluene or methyl alcohol or cyclohexanone or the water, emulsifier is one or more in WJD-100 or farming breast 500 or NP-10 or OP-10 or the Tween 80, and antifreeze is one or both in glycerine or the ethylene glycol.
The formulation of described composition is missible oil or microemulsion.
The preparation method of the compound pesticide composition of a kind of fluorine-containing worm nitrile and Rogor, after it is characterized in that earlier the solvent in fluorine worm nitrile, Rogor, the additive fully being mixed in the enamel stirred tank, add emulsifier and antifreeze in the additive, after stirring 30 minutes again, make a kind of fluorine-containing worm nitrile of missible oil or micro-emulsion form and the compound pesticide composition of Rogor.
The present invention adopts fluorine worm nitrile and the composite use of Rogor, and low toxicity, insecticidal spectrum are wide, and is quick-acting and lasting effect is good, show the extremely strong insecticidal activity of pest, with low cost, can prevent and treat the paddy rice various pests, be the comparatively desirable pesticide species of control rice grub, easy to use, safety.The formulation that this Recompounded pesticide is made can be produced needs according to enterprise and decided, and has to produce many advantages such as simple, efficient, that cost is low, and environment compatibility is good.This Pesticidal combination is different from existing other Pesticidal combinations, can suspension of pesticide resistance generation, reach the purpose of agricultural production and income.
Embodiment
Further specify the present invention below with reference to embodiment, following embodiment only is used to the present invention is described and to the present invention without limits.
Embodiment 1 is for verifying that the different proportioning consumptions with Rogor of fluorine worm nitrile are to the rice grub insecticidal effect, carried out the Toxicity Determination of the different proportionings of fluorine worm nitrile to rice grub with Rogor, be made into respective concentration according to percentage by weight in the table, carry out indoor insecticidal test, to measure co-toxicity coefficient, now result of the test is reported as follows:
Method of testing: adopt dipping feed method, promptly handle 20 4～5 age Chilo spp larvae, establish two repetitions, in contrast with the clear water dipping.The paddy rice cane in tillering stage of applying pesticides not is cut into the segment of 4-5 centimeter length, put into the soup of above compound concentration, flood taking-up in 1 minute, blot the soup on rice cane surface, put into bowl with blotting paper, put into again as 5 age 10 of Chilo spp larvaes, outer one deck preservative film that covers, pinking is some, places shady and cool place, check the dead borer population of larva after 24 hours, calculate lethality and corrected mortality then.Test data machine DPS software systems is as calculated handled, and obtains LC50, toxicity regression line and 95% confidence interval of each medicament.Statistics sees Table 1.
