Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing o-phenylenediamine insecticides and pymetrozine.
Background technology
The chemical structural formula of o-phenylenediamine insecticides A is as follows:
，
This insecticide is the new type disinsection immunomodulator compounds that Syngenta Co., Ltd announces, and disclosing its mechanism of action is at present ryanodine receptor agent, without more Experimental report or open, does not also have the site test in composite field open.
Pymetrozine, another name: pyrazinones, English name: pymetrozine, molecular formula: C
10h
11n
50, chemical name: 4,5-dihydro-6-methyl-4-(3-pyridine methylene amino)-1,2,4-3 (2H)-one, has efficient, low toxicity, high selectivity, the feature such as environmentally friendly, meets current Agrochemicals direction.Its structural formula is:
Its mode of action is unique, the influent pH of major effect insect, make its food refusal and dead, its preparation can be used for preventing and treating most of homoptera pest, especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect, be applicable to vegetables, ornamental plants, fruit tree, oranges and tangerines, paddy rice, cotton and multiple field crop, important aphids all on potato can also be controlled to reach the generation controlling potato virus disease.This medicine can penetrate in plant leaf blade very soon, and the longevity of residure reaches more than 1 month, without cross resistance, and to natural enemy high safety.In addition, pymetrozine and main metabolites thereof the leaching in soil is very low, exists only in topsoil, very little to the possibility of pollution of underground water under recommend use dosage.But pymetrozine is through extensive application in recent years, and insecticidal effect obviously declines, have a strong impact on the application prospect of this single dose.
The insecticide that Long-Time Service is single, insect is easy to develop immunity to drugs, and pesticide dosage is increased, and cause the adverse consequencess such as high poison, consumption are large, residual many, drug effect is poor, and effect field is more single.And research and develop the agricultural chemical compound that seems, then the R&D cycle is long, and screening compounds arrangement works is very numerous and diverse, and non-general research and development institution can bear.But the different mechanism of action and without the insecticide rational mixture by a certain percentage of cross resistance, crop disease prevention effect can be improved, reduce dosage, residual few, reduce environmental pollution, effectively reducing the pesticide resistance of crop, is the study hotspot of current medium and small research and development institution.

(5) toxicity test result and analysis
Table 1 o-phenylenediamine insecticides A, pymetrozine are to the indoor measurement result of diamond-back moth
As can be seen from the table, in the mixture of different proportion, its co-toxicity coefficient is all greater than 120, shows certain synergistic effect, wherein o-phenylenediamine insecticides A: pymetrozine be 7: 15 synergistic effect the most obvious, co-toxicity coefficient is 178.25.Result of the test shows, pymetrozine, o-phenylenediamine insecticides A two kinds of medicaments all have higher activity to diamond-back moth in room conditions, the result of the test of different proportion proportioning shows, by active ingredient o-phenylenediamine insecticides A: when pymetrozine is 5:17,7:15,9:13,11:11,13:9, all show stronger synergistic effect, wherein with o-phenylenediamine insecticides: when pymetrozine is 7: 15, synergistic effect is best.Suggestion carries out further field control effectiveness test to the mixture preparation of suitable proportion about 7:15 scope, to evaluate its field practical application effect.
Field experiment: field experiment control rice pest
(1) test method
The double-ridged horn of test in Hubei Province carries out, and experimental field soil is loam, middle fertility, and irrigation and drainage are convenient, and surrounding all plants double cropping rice.For before the medication of examination paddy rice, the rice is doing well.The Zhu little Ni ridge, minizone is in case string is filled with, and during dispenser, there is 3 ~ 4cm shoaling layer in field, water conservation 7d after medicine, tests four (2) for rice fulgorid low instar nymphs occurrence in peak period (September) medication in afternoon 1 time, to water 50kg/hm
2, secondly evenly slightly spray with workers and peasants 16 type knapsack hand sprayer, now paddy rice is in grouting mid-term, and field is mainly white-backed planthopper, is small brown rice planthopper, and 1 ~ 3 age nymph account for 90%.Dispenser same day is fine day, mean temperature of air 29.5 DEG C; After medicine, 7d is all without rain, weather on this test substantially without impact.
Investigate 4 times altogether, investigation insect population radix before medicine, after medicine, 2d, 7d, 14d investigate 1 time respectively.Take the parallel great-jump-forward random sampling 50 in every community point, 2 clumps often, totally 100 clumps of rice, clap with basin the borer population alive that method records white-backed planthopper, small brown rice planthopper respectively, then calculate its Rectifying efficacies (hereinafter referred to as preventive effect).
(2) drug effect computational methods
Borer population × 100% alive before Revision insect recluced rate (%)=(borer population of living after borer population one medicine of living before medicine)/medicine
Preventive effect (%)=(treatment region Revision insect recluced rate-check plot Revision insect recluced rate)/(100-is according to district's Revision insect recluced rate) * 100
(3) poisoning investigation method
After medicine, 2,7,14d observe paddy growth situation, estimate medicament to paddy rice all without poisoning.
(5) field control effectiveness test result of the test
Table 2 treatment agent prevents and treats rice hoppers field control effectiveness test result
As can be seen from Table 2, the mixture of 7% o-phenylenediamine insecticides A+15% pymetrozine combines the successful preventing and treating rice hoppers and is better than 50% pymetrozine WG contrast single dose, 7% o-phenylenediamine insecticides A+15% pymetrozine insecticidal effect of 14 days after medicine is respectively 92.57%, 93.03% and 94.26%, insecticidal effect increases progressively along with the increase of consumption, estimate according to field, substantially disease is not had with the paddy rice of 7% o-phenylenediamine insecticides A+15% pymetrozine, and growth fraction is more vigorous, and occur that disease is more with the paddy rice of 50% pymetrozine WG single dose, the disease plant much about about 10% of ratio complex preparation.In addition within the scope of test dose, plant growth is normal, and the poisoning phenomenon to paddy rice does not all appear in each treatment agent, illustrates that it is safe to paddy rice.
