Abstract
The invention relates to an insecticidal composition containing benclothiaz and dinotefuran. The insecticidal composition is characterized in that active components of the insecticidal composition are benclothiaz and dinotefuran and the rest is auxiliary components used in preparation of pesticide formulation; a weight ratio of the active component benclothiaz to the active component dinotefuran is 1-30: 1-30; the dosage form of the insecticidal composition may be a wettable powder, a suspending agent, a soluble liquid, an emulsion in water and a water dispersible granule; and the total weight of the active components benclothiaz and dinotefuran accounts for 5 to 40% of the total weight of the insecticidal composition. The active components benclothiaz and dinotefuran in the insecticidal composition have obvious synergistic effect; so an insecticidal spectrum is broadened, the usage amount of the insecticidal composition is reduced, prevention efficiency is improved, few residues are left, the action period of the insecticidal spectrum is long, resistance generation of insects is delayed, and environmental 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 MTI-446.
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:
。
The third generation nicotinic insecticide that MTI-446 (dinotefuran) is developed for Mitsui chemical company.The chemical constitution of itself and existing nicotinic insecticide is far from each other, and its tetrahydrofuran base instead of former chloro-pyridine base, chloro-thiazole base, not containing halogen.Meanwhile, also different with nicotine at aspect of performance, current people are referred to as " furans nicotine ".This medicament insecticidal spectrum is wide, has remarkable interior suction osmosis, and namely shows very high insecticidal activity at very low dosage.Its chemical structural formula is:
MTI-446 resembles brown planthopper, white-backed planthopper, small brown rice planthopper, rice leafhopper, rice spider rafter stinkbug, star stinkbug, green rice bug, redly the control of bearing the rice grub such as mixed worm, rice cylinder water snout moth's larva of fleahopper, rice must have efficient effect; To Phytophthira, aleyrodid class, a red-spotted lizard class, unaspis shield kuwana, the green stinkbug of Zhu, peach fruit borer, tangerine lyonetid, the thin moth of tea, striped flea-beetle, beans veterinary antibiotics insects such as fly of diving, also there is efficient effect.
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.

Field experiment example: field experiment control rice pest
(1) test method
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 28 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 30 in every community point, 2 clumps often, totally 60 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, the mixture of 6%benclothiaz+12% MTI-446 combines the successful preventing and treating rice hoppers and is better than 20% MTI-446 SC contrast single dose, 6%benclothiaz+12% MTI-446 insecticidal effect of 14 days after medicine is respectively 94.1%, 93.63% and 93.85%, insecticidal effect increases progressively along with the increase of consumption, estimate according to field, substantially disease is not had with the paddy rice of 6%benclothiaz+12% MTI-446, and growth fraction is more vigorous, and occur that disease is more with the paddy rice of 20% MTI-446 SC single dose, the disease plant much about about 12% 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.
