Abstract
The invention relates to insecticide composition for corn. The insecticide composition for the corn contains a bisamide compound and an anabasine compound and is especially a seed coating agent, wherein the bisamide compound is any one of chlorantraniliprole, cyantraniliprole and tetra-chlorantraniliprole; the anabasine compound is any one of thiamethoxam, imidacloprid, clothianidin and dinotefuran; and the weight ratio of the amide compound to the anabasine compound is (1:10)-(10:1). The insecticide composition for the corn has an obvious synergistic effect on control of athetis lepigone, ostrinia nubilalis and plant hopper and resistance to the insecticide composition for the corn is reduced.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination for corn containing bisamide compounds and anabasine compound, described Pesticidal combination particularly seed coat agent.
Technical background
Seed coating technology is a kind of seed treatment new technology grown up in traditional seed soaking or seed dressing technical foundation.By seed that is dry or moisture state, wrapping with compositions such as the agricultural chemicals containing binding agent, make to form the protective layer with certain function and coated intensity outward at seed, this process becomes seed pelleting, and the composition wrapped in outside seed is seed coat agent.Seed coat agent imbibition and not dissolved in soil, contained agricultural chemicals is slow releasing with the germination and growth of seed, so seed coat agent has kill soil insect, the effect such as insect in seedling stage, finally reaches preventing disease pest control, protects face strong sprout, improves the object of output.
Current common corn seed coating agent is mainly used in control soil insect and small brown rice planthopper, and cannot reach to seedling stage other insects as: 2 committee noctuid, corn borers etc. have equal preventive effect, make the later stage still need spray pesticide, not in time, insect pest is large causes the underproduction in various degree when occurring in control.
Rynaxypyr, bromine cyanogen insect amide, four chlorantraniliproles are bisamide insecticides, Main Function mechanism is by efficiently activating insect ryanodine receptor, make the calcium ion in calcium storehouse in its excessive release cells, destroy insect cell device intra-and extra-cellular calcium ionic equilibrium, thus it is dead to cause insect to be paralysed.Have interior absorption in various degree, root absorption, xylem conducts from bottom to top.Can effectively prevent and treat Lepidoptera, Semiptera and coleopteran pest.
Diacloden, Imidacloprid, clothianidin, MTI-446 are anabasine insecticide, Main Function mechanism is by Selective Control insect nerve system nicotinic acetylcholine esterase acceptor, block the normal conduction of insect CNS, thus cause insect to occur paralysis and then death.There is systemic action, can effectively prevent and treat the insects such as Homoptera, coleoptera, diptera and Lepidoptera, both can be used for cauline leaf process, also can be used for soil, seed treatment.
Summary of the invention

Embodiment
Below in conjunction with embodiment, the present invention is described further, but the present invention is not limited to this.
Carry out statistical analysis with DPS software, calculate the LC of each medicament
50, and calculate mixture according to the abundant method of Sun Yun spend coefficient (CTC value) together.
Actual measurement toxicity index (ATI)=(standard agent LC
50/ reagent agent LC
50) × 100.
In theoretical toxicity index (TTI)=A medicament toxicity index × mixture A percentage composition+B medicament toxicity index × mixture in the percentage composition of B.
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as synergistic effect; Co-toxicity coefficient (CTC)≤80 shows as antagonism; 80 < co-toxicity coefficient (CTC) < 120 show as summation action.
