Description
[technical field]
The invention belongs to technical field of pesticide.More particularly it relates to an the agricultural pesticide composition containing sulfur insect amide and chlopyrifos, further relate to the purposes of described agricultural pesticide composition.
[background technology]
Rice leaf roller, striped rice borer and planthopper are to endanger several insects the most serious in China's Rice Production, if preventing and treating is not in time, can cause heavy losses to Rice Production.Chemical prevention is to control the Main Means that above-mentioned insect is caused harm, but constantly using along with chemical agent, resistance problem becomes increasingly conspicuous, and in agricultural production real process, pest resistance to insecticide problem is the key factor affecting pest controling effect.Difference effective ingredient is carried out composite can expanding prevention spectrum and improve preventive effect, be the effective measures of pest resistance treatment.
Sulfur insect amide (HY366) can be combined with ryanodine receptor, causes Ca2+Out of control and the loss of release, makes the contractile function of muscle cell paralyse, is the compound of brand-new mechanism of action.Insect after chemicals treatment shows as feed stopping, weak, regurgitation and Muscle paralysis rapidly, until dead.This insecticides insecticidal spectrum is wide, longevity of residure length, toxicity are low, environmentally friendly, with existing each insecticides no interactions resistance.Can effectively prevent and treat each Species of Lepidopterous Insect Pests and some coleoptera larvae, adult, it is also possible to be used for preventing and treating the insect such as Formica fusca, Coptotermes formosanus Shtrari..
Chlopyrifos (Chlorpyrifos) is acetylcholinesteraseinhibitors inhibitors, belong to thiophosphate insecticides, be a kind of efficiently, the organophosphorus insecticide of wide spectrum, there is stomach toxicity, tag, fumigate triple role, chewing type multiple in Oryza sativa L., Semen Tritici aestivi, Cotton Gossypii, fruit tree, vegetable, Camellia sinensis and sucking pest are respectively provided with good preventive effect.Different pesticide species mixtures are the common methods of preventing and treating agricultural resistant insect.Screened by formulation of pesticide, filter out rational formula, actual prevention effect can be effectively improved, reduce dosage, reduce cost, delay the generation of pest resistance to insecticide, extend the service life of medicament, be the important means of integrated pest management.
But, there are some technological deficiencies in these prior aries, is not met by current agricultural production needs, therefore also needs to the Pesticidal combination efficiently preventing and treating Oryza sativa L., vegetable insect disease that exploitation is new, and this is extremely important for advancing agricultural large-scale development.

Two, bioactive mensuration
In order to further appreciate that the virulence of sulfur insect amide and chlopyrifos compositions, carry out a large amount of formulation screening test.
Pesticidal combination biological activity determination of the present invention is as follows:
Infusion process is adopted to carry out rice leaf roller and striped rice borer test.Evaluate SOP (insecticide volume) according to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.7-2006, NY/T1154.14-2008) and initiative pesticide bioactivity to carry out, measure sulfur insect amide and chlopyrifos single dose LC50With mixture LC50。
Concrete operations mode is as follows: Oryza sativa L. tender stem stalk is cut into a cun section, submergence 15s in test medicinal liquid, places in the culture dish being lined with absorbent paper, and 5 sections of every ware dries.Connect test with worm (2 mid-term in age larva) according to 15/ware, be placed in observation ward.If clear water is comparison, often processes and repeat 4 times, after 3d, check result.Touch polypide with brush pen, reactionless be considered as dead worm.
Planthopper test uses Brown Planthopper (Nilaparvatalegen), raises worm kind (carrying out illumination according to 14h/d at temperature 27 DEG C) with rice seedling for indoor throughout the year.Indoor feeding is selected to be for experiment to the nymph that 3 mid-terms age are consistent.Adopt nebulization.Test rice seedling selects water culture to cultivate the rice seedling (being about 3～4cm) to 2 leaf 1 hearts, cleans standby with clear water.4～6 rice seedlings Quartz Album sand are fixed in the culture dish of Φ 7cm, meet CO2Brown Planthopper 3 nymph in mid-term in age 30 of anesthesia, it is placed under Potter spray tower quantitative (2.5mL) spraying and processes that (pressure is 5Ib/iW2, settling amount is 4.35mg/cm2), test sets the corresponding organic solvent without medicament and processes as compareing, and often processes and repeats 4 times, covers with transparent plastic cup after spraying, it is placed in observation ward at temperature 27 DEG C illumination 14h, check result after 3d, touch polypide with brush pen, reactionless be considered as dead worm.
Add up the borer population alive of each process and total borer population, calculate the mortality rate of each process and corrected mortality (Abbott ' s formula)；Carry out data analysis statistical by " DPS data handling system " V14.50 professional version, obtain regression straight line, LC50Value.Calculate toxicity index by the abundant method of Sun Yun (Sun etc., 1960), following formula calculate and obtain co-toxicity coefficient:
Toxicity index × the A of theoretical mixed toxicity index (TTI)=A content (%) in using with
Toxicity index × the B of+B content (%) in using with
When co-toxicity coefficient is more than 120, it was shown that this mixture has potentiation；And co-toxicity coefficient less than 80 time, it was shown that this mixture has antagonism；And co-toxicity coefficient more than 80 less than 120 time, it was shown that this mixture has summation action.
