Abstract
The invention relates to an insecticide compound which comprises guadipyr and has the complementary action and the synergetic effect. The insecticide compound comprises effective active ingredients A and B. The effective active ingredient A is guadipyr and the effective active ingredient B is selected from any one of the following insecticides: abamectin and emamectin benzoate, wherein the weight ratio of the effective active ingredients A and B is (1 to 50):(70 to 1). Auxiliaries and fillers are added into the effective active ingredients to form wettable powder, missible oil and a suspending agent. The insecticide compound disclosed by the invention can be used for delaying the generation of the pest resistance to insecticides and can be widely applied to the field of agriculture.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains penta pyrrole worm guanidine, wherein A is selected from penta pyrrole worm guanidine, and B is selected from a kind of in AVM, the emamection benaoate.
Technical background
Sucking pest is bigger in a garden plant pests monoid, and like aphid, plant hopper, aleyrodid, leafhopper, thrips, their individualities are little; The initial stage of origination shape of often being injured is not obvious, be prone to ignored by people, but numbers of poles is many; Often infest on spray, leaf, bud, bud, the fruit, draw water, rob its nutrition; Cause branches and leaves and steamed twisted roll bent, even whole strain is withered or dead, causes China crops therefore to suffer heavy losses every year.So the general use of insecticide in most farmlands comes controlling sucking insects.But high strength ground use chemical pesticide increasingly sharpened such pest resistance to insecticide development, increased the insect treatment cost and difficulty has also caused serious food and environment residue of pesticide.
AVM is a kind of efficient, high selection, green, environment-friendly type, biological source insecticide; Emamection benaoate is a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product AVM B1, and it has super-high-efficient, low toxicity (preparation is closely nontoxic), noresidue, the nuisanceless characteristics that wait biopesticide.In recent years, AVM and emamection benaoate are used for controlling sucking insects, lepidoptera pest etc. all has good effect, but its quick-acting is poor slightly, and long-term the use, and insect produces resistance to it.
Penta pyrrole worm guanidine structure:
Summary of the invention
In view of this, the objective of the invention is to propose a kind of Pesticidal combination, make its quick-acting is good, can prevent pest resistance to insecticide generation or delaying drug resistance speed, the Pesticidal combination that use cost is low, preventive effect is good.
The present invention realizes through following technical scheme:
A kind of Pesticidal combination that contains penta pyrrole worm guanidine is made up of A and two kinds of active active ingredients of B, and A is penta pyrrole worm guanidine, and B is selected from a kind of in AVM, the emamection benaoate.
Wherein, the mass ratio of said effective active composition A and B is preferably 1～50: 70～1, more preferably 1～40: 50～1, most preferably be 5～30: 30～5.
AVM, English name abamectin is a kind of farm antibiotics, its significant feature mode be tag, stomach toxicity, penetration be strong.It is a kind of macrolide disaccharide compounds, is the natural products that from edaphon, separates, and insect and mite class is had tag with stomach poison function and faint fumigation action is arranged, no systemic action.But it has very strong osmosis to blade, can kill subepidermal insect, and the longevity of residure is long, but lethal effect is slower.Emamection benaoate, another name first dimension salt, methylamino avermectin, chemical name 4 "-Biao-methylamino-4 "-the deoxidation abamectin benzoate; Be a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product AVM B1, it has super-high-efficient, low toxicity (preparation is closely nontoxic); Noresidue, the nuisanceless characteristics that wait biopesticide, the double again action of contace poison of existing stomach poison function; (have good effect under 0.084～2g/ha), and in the process of pest control, beneficial insect is not injured, help integrated control at low-down dosage insect; Enlarged insecticidal spectrum in addition, reduced toxicity people and animals.
Penta pyrrole worm guanidine is first nitro of our seminar of China Agricultural University initiative aminoguanidine insecticides that contracts, agriculture chemical registration is checked and approved " penta pyrrole worm guanidine " by name, English name " Guadipyr "; Chemical name 1-nitro-3-(6 '-chloro-3 '-picolyl)-4-valeraldehyde aminoguanidine that contracts; Female, great and mighty or powerful mouse acute oral LD50＞5000mg/kg.BW belongs to little poison, is non-stimulated level to lagophthalmos, skin irritatin intensity; Abnormal (sensitization) intensity of skin is the I level; Belong to weak sensitizer, the Salmonella reversion test result is negative, rat acute toxicity is had only about 1/10 (Imidacloprid is 450mg/kg.BW) of Imidacloprid.Imidacloprid belongs to high poison level, and penta to adjoin the worm guanidine be low toxicity level, and the absorption toxicity to honeybee is lower 10 times than Imidacloprid in addition.The result shows, penta pyrrole worm guanidine has efficiently, low toxicity and the good characteristic of safety.Have the architectural feature of anabasine insecticide and sodium-ion channel inhibitor insecticides concurrently; Has desinsection pedigree widely; Characteristics with multiaction target, this product all has the better prevention effect to multiple suckings pest such as aphid, plant hopper, cotton bollworms.
The Pesticidal combination of described penta pyrrole worm guanidine and jinggangmeisu, penta pyrrole worm guanidine is different with the mechanism of action of jinggangmeisu, and both are composite, have certain complementation and synergistic effect.
