In the composition, the two active components of benclothiaz and flonicamid can be prepared into preparations applicable to agricultural application and have obvious synergistic effect, the insecticidal spectrum is enlarged, the amount of pesticides is reduced, the control efficiency is improved, the residues are few, the lasting period is long, the generation of drug resistance of injurious insects is delayed, and the environment protection is benefited.
Description
Technical field
The present invention relates to technical field of pesticide combination, be specifically related to a kind of Pesticidal combination containing benclothiaz and flonicamid.
Background technology
Benclothiaz is considered to nematocide usually, thinks the highest to nematode activity, and since compound structure is announced, seldom see the activity research to other field or other insects, the more rare application in agriculture chemical compounding field, its chemical structural formula is as follows:
。
Flonicamid mainly activates blue Buddhist nun's alkali acceptor, and the calcium ion of release smooth muscle and the interior storage of striated muscle cell, causes muscle to regulate weak, paralysis, until last insect death.This active ingredient shows mammal and the extremely significant selective difference of insect blue Buddhist nun's alkali acceptor, substantially increases mammal and other vertebrate safeties.O-formammidotiazol-benzamide insecticide all has good control effects to lepidopterous Noctuidae, Pyralidae, Carposinidae, tortricid, miller section, diamond-back moth section, Gracilariidae etc., can also control the multiple non-lepidoptera pests such as coleoptera Culculionidae, Chrysomelidae, diptera Agromyzidae, Bemisia tabaci.Have very outstanding preventive effect to larva, shortcoming is to adult controlling limited efficiency, does not have ovicidal action, and Uptake and translocation effect is not strong.
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.

Test is carried out at the double-ridged horn in Luo Wan village, journey market town, Jianli County, Jingzhou City of Hubei Province, 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 medication in afternoon 1 time, to water 50kg/hm
2, evenly slightly spray with workers and peasants 16 type knapsack hand sprayer, time paddy rice be in grouting mid-term, secondly 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.
(2) investigation method
Investigate 4 times altogether, investigation insect population radix before medicine, 2d after medicine, 7d after medicine, after medicine, 14d investigates 1 time respectively.Take the parallel great-jump-forward random sampling 15 in every community point, 2 clumps often, totally 30 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).
(3) drug effect computational methods
Preventive effect (%)=
× 100;
(4) 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, 8%benclothiaz+14% flonicamid is better than 20% flonicamid SC contrasts single dose by the weight portion mixture combination successful of preventing and treating rice hoppers of 8: 14, 8%benclothiaz+14% flonicamid insecticidal effect of 14 days after medicine is respectively 94.01%, 90.06% and 95.35%, insecticidal effect increases progressively along with the increase of consumption, estimate according to field, substantially disease is not had with the paddy rice of 8%benclothiaz+14% flonicamid, and growth fraction is more vigorous, and the paddy rice of 20% flonicamid SC single dose occurs that disease is more, the disease plant much about about 7% 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.
