The insecticidal composition is used for controlling grubs, mole crickets, cutworms, scarabs, longhorn beetles, weevils, root-knot nematodes, snout moths larvae, noctuid, armyworms, aphides, thrips, plant hoppers or whiteflies on corn, rice, sugar cane, bananas, vegetables or peanuts; deficiencies that the conventional insecticides for controlling insects under the ground and on the ground is high in toxicity, unsafe to produce and use, high in resistance, poor in control effect, and high in use cost are overcome; and compared with the prior art, the insecticidal composition has the advantages of broad insecticidal spectrum, good control effect, long lasting period, low use cost, safety and less environmental pollution.
Description
Technical field
The present invention relates to technical field of pesticide, specifically a kind of Pesticidal combination that contains MTI-446 and Benfuracard micro.
Background technology
MTI-446, English name: Dinotefuran, molecular formula: C
7H
14N
4O
3, chemical name: 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, chemical structural formula:
MTI-446 is the third generation nicotinic insecticide of Mitsui chemical company exploitation, and is different from the chemical constitution of existing nicotinic insecticide, and chloro-pyridine base, chloro thiazolyl before its tetrahydrofuran base has replaced do not contain the halogen family element.Simultaneously, also different with nicotine at aspect of performance, so people are referred to as " furans nicotine " at present.
The MTI-446 mechanism of action be Main Function in insect neurotransmission system, thereby make insect cause paralysis performance insecticidal action.MTI-446 has tags and stomach poison function, and absorption is strong in the root, quick-acting height, and the lasting period is long, and insecticidal spectrum is wide, and sucking insect is had excellent preventive effect, and has namely shown very high insecticidal activity at very low dosage.Be mainly used in preventing and treating aphid, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof on the various crop such as wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf, simultaneously coleoptera, diptera, Lepidoptera, beetle order and total wing order insect are had efficiently, and the sanitary insect pests such as blattaria, termite, housefly are had efficiently.MTI-446 is high to crop, people and animals and environmental safety, and is fool proof to mammal, without teratogenesis, carcinogenic and mutagenicity; Toxicity to aquatile, birds and honeybee is very low, uses safety.It was introduced in Japan in 1993, obtained registration at the countries in Asia take Korea S as representative, this country and European Countries later on.
Benfuracard micro, English name: benfuracarb, molecular formula: C

Embodiment
In order to study the composite enhancing proportions of MTI-446 and Benfuracard micro, the inventor has carried out indoor joint toxicity measuring test to MTI-446 and Benfuracard micro.
Indoor joint toxicity measuring test 1
Test controlling object: rice-stem borer 3 instar larvaes.
Test method: dip method, each concentration for the treatment of are established 4 repetitions, and each repeats 30 examination worms.
Test arranges following 12 processing:
(1) No. 1 Benfuracard micro: MTI-446=1:30 of mixture
(2) No. 2 Benfuracard micro: MTI-446=1:20 of mixture
(3) No. 3 Benfuracard micro: MTI-446=1:10 of mixture
(4) No. 4 Benfuracard micro: MTI-446=1:5 of mixture
