Description
Technical field the present invention relates to the agriculture chemical compounding technical field, namely relates to a kind of two yuan of Pesticidal combinations that are mixed take ethyl pleocidin and indoxacarb as active ingredient.
The background technology ethyl pleocidin is a kind of pleocidin insecticides of novelty, is the second generation product of pleocidin.It has well solved the good disinsection effect of pleocidin to vegetable crop, but the undesirable problem of insect pest control to crops such as fruit and nuts, the pomaceous fruit heart-eating worm codling moth that especially can not prevent and treat pleocidin has special efficacy, and its insecticidal spectrum is wider than pleocidin simultaneously.In addition, it also has low toxicity, low-residual, fast to Natural Enemies of Insects safety, natural decomposition, and obtains U.S.'s " presidential green chemical Challenge Awards ".
Indoxacarb; 7-chloro-2; 3,4a, 5-tetrahydrochysene-2-[methoxycarbonyl (4-Trifluoromethoxyphen-l) carbamoyl] indeno [1; 2-e] oxadiazine-4a-carboxyl ester; be a kind of insecticide of du pont company Development and Production, the mechanism of action is main by the sodium-ion channel in the blocking-up insect nerve cell, makes the nerve cell loss of function; it is poor, final dead to cause target pest to benumb, coordinate.Indoxacarb has good lipophilicity in addition, only has to tag and stomach poison function, though there is not systemic activity, has good resistance of rainwater washing against performance.Can prevent and treat lepidoptera pest such as cotton bollworm, cabbage caterpillar, oriental tobacco budworm, diamond-back moth, beet armyworm, prodenia litura, leaf rollers etc.
Using with of insecticide is one of strategy the most frequently used in the current Chemical Control of Harmful Insects.Agriculture chemical compounding has synergy, addition, three kinds of distinct results of antagonism, even if composite between two kinds of agricultural chemicals because the different synergy degree of proportioning are also different, have or even antagonism.The obvious composition of synergy by testing sieve is selected not only can improve the preventive effect to lepidoptera pest, reduces the usage amount of chemical pesticide, reduces production costs, and delays the generation of pest resistance to insecticide., find can to produce good synergistic effect after biopesticide ethyl pleocidin and indoxacarb is composite to the research of agriculture chemical compounding through the laboratory, insecticide efficiency improves greatly, and more low toxicity, environmental protection.And about the composite of ethyl pleocidin and indoxacarb compound and use and there is no at present the people and reported.
The purpose of this invention is to provide a kind of composition of ethyl pleocidin-indoxacarb, it has higher virulence to insects such as rice leaf roller, can reduce the cost accounting of lepidoptera pest.
Summary of the invention technical problem to be solved by this invention provides a kind of preferably composite insecticides of ethyl pleocidin and indoxacarb of lepidoptera pest effect of preventing and treating.
Insecticides main component of the present invention is ethyl pleocidin and indoxacarb, two kinds of compositions in composition take weight ratio as 25～75: 75～25 carry out reasonably composite, through a series of screening test, the obvious composition of selective advance, strengthen quick-acting, reducing pesticide cost is key point of the present invention.
The invention has the advantages that:
1. ethyl pleocidin acts on nAChR, but also variant with nicotinic insecticide.And indoxacarb makes the nerve cell loss of function mainly by the sodium-ion channel in the blocking-up insect nerve cell, and it is poor, final dead to cause target pest to benumb, coordinate.Two kinds of agricultural chemicals are different to the mechanism of action of insect, can delay the generation of pest resistance to insecticide, are the alternative of medicament that rotate.
2. above-mentioned mixture reasonable mixture ratio, stronger to the virulence of the lepidoptera pests such as rice leaf roller, co-toxicity coefficient is higher, has stronger synergistic effect, is that a class is efficient, the mixture preparation of low toxicity.
Embodiment
1. reagent agent
60g/1 ethyl pleocidin DowElanco China Ltd; 150g/1 indoxacarb Du Pont China Holding Co., Ltd..
2. for examination worm source:
Gather the adult of rice leaf roller from the rice field, in the indoor dependent insect cage that the paddy rice in tillering stage is housed, wait to lay eggs.The paddy rice that produced ovum is placed on incubator and raises the raising condition: 28 ℃, and the light dark period of 60%RH and 16:8.Test Deng giving birth to test with newly hatched larvae after the ovum hatching.
3. single dose assay method
Method according to foundation such as Zheng Xuesong is that dipping seedling method monitoring rice leaf roller is to the susceptibility of insecticide.
Rice seedlings (approximately 25cm the is high) cauline leaf in three weeks of growth is inverted, is immersed in the suspension of variable concentrations medicament, then naturally dry, until without open fire.In culture dish (diameter 7cm), put into 3 of the suitable filter paper of size, splash into a small amount of water with glue head dropper and make filter paper moistening.It is long that rice leaf behind the dipping is cut into 5cm, and about 30 of upper blade fragments are put on the filter paper of culture dish.Gently newly hatched larvae is transferred to banister bruss on the rice leaf of culture dish.
The culture dish of access larva is put at 25 ℃, raises in the incubator of 60%RH and 16:8 light dark period, the check result after 3 days (72 hours) that connects worm.Each medicament is established 5 concentration, and each processes 3 repetitions, and each repeats 15 newly hatched larvaes.Death standard touches polypide with writing brush, and larva can not the coordinated movement of various economic factors be death standard, and the contrast lethality is efficiency test less than 20%.
4. data are processed
Adopt POLO Plus software to calculate the toxicity regression formula.Calculating parameter comprises: toxicity regression formula, slope b value and standard error, LC
50Value and 95% confidence limit.
5. joint toxicity measuring method
The lab screening of composite formula adopts the abundant co-toxicity coefficient method of Sun Yun:
Toxicity index (TI)=(LC of standard medicament
50The LC of/reagent agent
50) * 100
The actual toxicity index of mixture (the ATI)=alone LC of medicament A
50The LC that/medicament A and B use with
50) * 100
The theoretical toxicity index (TTI) of mixture=ATI (A) * a+ATI (B) * b
A: the percentage composition of expression medicament A in mixture;
B: the percentage composition of expression medicament B in mixture.
Co-toxicity coefficient CTC=(the theoretical toxicity index TTI of the actual toxicity index ATI/ mixture of mixture) * 100
According to the regulation of the Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC, the criterion of mixture prescription synergy is: co-toxicity coefficient is synergistic effect greater than 120; Co-toxicity coefficient 80-120 is summation action; Co-toxicity coefficient is antagonism less than 80.
The selection of best proportioning is with co-toxicity coefficient and the LC of mixture
50(or LD
50) two indexs of value weigh, i.e. higher the and LC of co-toxicity coefficient
50(or LD
50) value minimum (namely surveying the toxicity index maximum).
Table 1 ethyl pleocidin composition is to the toxicity test result of rice leaf roller
As can be seen from the table, in different ratios was mixed, its co-toxicity coefficient showed certain synergistic effect, wherein ethyl pleocidin all greater than 120: indoxacarb synergistic effect in 1: 1 o'clock is the most obvious, and co-toxicity coefficient is respectively 285.78; Secondly be ethyl pleocidin: 1: 2 o'clock co-toxicity coefficient of indoxacarb is 281.28.Result of the test shows, ethyl pleocidin, two kinds of medicaments of indoxacarb all have higher activity to seed rice leaf roll snout moth's larva under the indoor conditions, the result of the test of different proportionings shows, it is 3: 1 in effective ratio, 1: 1,1: 2,1: 3 o'clock, all show stronger synergistic effect, wherein best take the two ratio as 1: 1 and 1: 2 o'clock synergistic effect.
