Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide, specifically is a kind of indenes worm prestige and pyridaphethione compounded pesticides.
Background technology
Indenes worm prestige (indoxacarb), chemical name are 7 one chlorine one 2,3; 4a, 5 one tetrahydrochysenes 1 (methoxycarbonyl group (4-trifluoromethoxy benzaldehyde base) carbamoyl) indenes penta (1,2 one e) (1; 3,4) diazine one 4a monocarboxylic acid methyl esters, be the extensive use of agriculture and garden field uh the diazines insecticide; It makes the nerve cell loss of function through blocking-up insect nerve cell sodium-ion channel, belongs to insect sodium-ion channel inhibitor.Indenes worm prestige with tag with stomach poison function be main; There is not cross resistance in other insecticides; And to natural enemy insect safety; Can be used for the insect comprehensive regulation (IPM) and resistance management (RPM); Be used to prevent and treat agriculture and garden crop pest such as rice leaf roller, striped rice borer, paddy stem borer, beet armyworm, tomato moth, diamond-back moth, cotton bollworm, cotten aphid, rice stinkbugs such as paddy rice, vegetables, cotton, fruit tree, tea tree, gardening, flowers, fruit eats into moth, potato leaf is first-class, and each instar larvae is all had good control efficiency.But because the agricultural cost of crop pests such as control paddy rice, vegetables is high, to a certain degree limit its popularizing area, particularly some economically less developed regions be difficult to promote.In addition, repeat to be prone to make insect to develop immunity to drugs fast with a large amount of the use.
Pyridaphethione is a kind of efficient, the low toxicity of pressing that Co., Ltd. develops the beginning of the seventies by Mitsui east, the broad-spectrum organic insecticide of low-residual.It is a kind of tagging and stomach insecticide, and insecticidal spectrum is wide.Various pests on the crops such as paddy rice, wheat, cotton, rape, vegetables, fruit tree has good control efficiency.It also is a kind of low toxicity organophosphorous pesticide simultaneously, and safe in utilization, along with the forbidding of country to five high malicious organic phosphor kinds, pyridaphethione is one of desirable alternative kind.But because long-term a large amount of the use descends rapidly to some resistant insect preventive effects, consumption also increases, therefore alternately or composite use can continue pesticide resistance, improve preventive effect simultaneously.
In order to overcome the problems referred to above, research department all improves indenes worm prestige or pyridaphethione drug effect, reduces dosage with other mixed pesticides both at home and abroad, delays pesticide resistance and produces, and enlarges insecticidal spectrum simultaneously and reduces cost.Yet, still do not have the play-by-play that indenes worm prestige and pyridaphethione are used the control pest with at present both at home and abroad.
Summary of the invention
The purpose of this invention is to provide a kind of to indenes worm prestige and pyridaphethione compounded pesticides to pest controling effect is good, insecticidal spectrum is wide, cost is low.
Indenes worm prestige of the present invention and pyridaphethione compounded pesticides are that wherein the weight ratio of indenes worm prestige and pyridaphethione is 1: 1-50 with indenes worm prestige and the pyridaphethione pesticidal preparations as active component.

Biologicall test test one: indenes worm prestige, pyridaphethione and different proportioning are to the toxicity test of rice leaf folder
With reference to the determination method that FAO recommends, adopt drop method to carry out Toxicity Determination.To supply the reagent agent to become 5 series concentration with acetone diluted; Select for use consistent rice leaf roller 3 instar larvaes of worm attitude to place in the 9cm culture dish, slightly anaesthetize with CO2, with micro-dropper that medicine liquid droplet is central in the pronotary of examination worm then; Every cephalont point drops physic liquor 1 μ l; Every processing repeats 3 times with 20 of worms, handles as blank with acetone and emulsifier TritonX.Treated rice leaf roller examination worm treats promptly to move in the 12cm culture dish after the solvent evaporates, adds fresh light green rice leaf; Preserve moisture with cotton balls, put into 28 ℃ of incubators and isolate the recovery raising, periodicity of illumination is 16L: 8D; Inspection larvae alive number calculates lethality and corrected mortality behind the 48h.Obtain virulence regression equation and LD50 with the probit value method; Method according to the abundant proposition of Sun Yun is calculated co-toxicity coefficient; Co-toxicity coefficient greater than 120 for synergistic effect; Co-toxicity coefficient is a summation action between 80～120, co-toxicity coefficient less than 80 be antagonism, carry out the pharmacy effect evaluation as standard.The computing formula of co-toxicity coefficient is following:
Toxicity index (ATI)=standard medicament LC50 or LD50 * 100
Supply reagent agent LC50 or LD50
The percentage composition of A in ATI * mixture of percentage composition+medicament B of A in ATI * mixture of theoretical toxicity index (TTI)=medicament A
Co-toxicity coefficient (CTC)=mixture actual measurement toxicity index (ATI) * 100
The theoretical toxicity index (TTI) of mixture
The result sees that table 1. is visible by table 1; Indenes worm prestige and pyridaphethione are mixed in the ratio of 1: 60,1: 40,1: 20,1: 10 and 1: 1; Its virulence to rice leaf folder all shows as obvious synergistic effect, and co-toxicity coefficient (CTC) is 128.76,148.68,217.28,187.82,157.20.
