Abstract
The invention discloses an acetamiprid-pirimicarb pesticide compound monitoring Woolly apple aphid and yellow aphid, the effective ingredients of said pesticide compound are compound of acetamiprid and pirimicarb, the weight ratio between acetamiprid and pirimicarb is in the range of 1:20-1:2, the effective ingredient of pesticide compound is 5-30wt%, the compound of acetamiprid and pirimicarb which are effective ingredients can be made into creaming agent, micro-emulsion and other agents, for preventing the two kinds of aphid injuries Woolly apple aphid and yellow aphid at the same time, the effect of monitoring two kinds of aphid injuries at one time is significant, while it is safe for natural enemies of pest. So using the pesticide compound according to the invention is good for reducing the control cost and optimizing the pest integrated control system.
Description
One, technical field:
The present invention relates to a kind of composition pesticide of prevention and control plant aphids, particularly relate to a kind of composition pesticide that contains Acetamiprid and Aphox that can control wooly aphis and two kinds of aphid evils of yellow aphids simultaneously.
Two, background technology:
The cultivated area of China's apple surpasses 2,000,000 hectares, and wooly aphis and yellow aphids are current important controlling objects.Wooly aphis is a kind of important plant quarantine object, spreads rapidly in each apple main producing region in recent years, and this worm breeds fast and secretion has the wax protection, and difficulty of prevention and cure is bigger, and is quite serious to apple tree harm.At present, the leading medicine of control woolly aphid is a chlopyrifos, and the shortcoming of this medicine is dangerous to pest natural enemy, and long-term the use destroyed seriously orchard ecology; The efficient medicament of control apple yellow aphid has Acetamiprid, but we find that in actual applications this medicament is relatively poor to the control efficiency of wooly aphis, and common dose kills and wounds also bigger to natural enemy.Because the emergence period basically identical of wooly aphis and yellow aphids, lack on the market to two kinds of insect a drugs can hold concurrently and control and to the safer medicament of natural enemy.Aphox is to be developed by Britain's ICI Imperial Chemical Industries nineteen sixty-five, and 1969 as special-purpose aphicide popularization.Good to the aphid quick-acting on the plants such as fruit tree, cereal, vegetables under recommended density, natural enemy of aphid such as ladybug, syrphus fly and aphid cocoon honeybee are had no adverse effects.Show through the test of our indoor biometrics, Aphox to the activity of wooly aphis apparently higher than apple yellow aphid.Aphox and Acetamiprid exist complementary when holding concurrently two kinds of aphids of control.Look into newly through data and to show, do not see the relevant report that has both to be mixed.For this reason, the medicine of a kind of double control wooly aphis of developmental research and two kinds of aphid evils of yellow aphids is very important.
Three, summary of the invention:
The objective of the invention is the action compensating that utilizes Aphox and Acetamiprid when prevention and control wooly aphis and two kinds of aphids of yellow aphids, to exist, respectively get the chief, overcome the problem that exists separately, by screening the rational proportion of synergy or summation action is arranged, provide a kind of a drug can effective prevention and control wooly aphis and the Acetamiprid pirimicarb pesticidal compositions of two kinds of insects of yellow aphids.
Technical scheme of the present invention:
The Acetamiprid pirimicarb pesticidal composition of a kind of double control wooly aphis and yellow aphids is provided, and wherein active ingredient is Acetamiprid and Aphox, the weight ratio scope between the two is generally 1: 20～and 1: 2, preferable range is 1: 10～1: 4.The percentage by weight that the two active ingredient accounts for composition pesticide is 5～30%.Utilize the prior dosage form process technology, above-mentioned composition pesticide can be mixed with missible oil or microemulsion formulation.The emulsifiable concentrate prescription is: described active ingredient 10～30%, organic solvent 45～70%, cosolvent 10～15% and emulsifier 10～15%; Micro-emulsion formulation is: described active ingredient 5～20%, and organic solvent 10～20%, cosolvent 10～15%, emulsifier 10～40%, all the other are water.Wherein said organic solvent is toluene or dimethylbenzene, and cosolvent is methyl alcohol or ethanol, and the emulsifier in the emulsifiable concentrate is OP, and the emulsifier in the microemulsion is the mixture of OP and neopelex.
The application of Acetamiprid pirimicarb pesticidal composition in prevention and control wooly aphis and yellow aphids of described double control wooly aphis and yellow aphids is equally applicable to the harmful prevention and control of various aphids that take place on the crops such as other fruit tree, vegetables, flowers and grain.
Positive beneficial effect of the present invention:
1, can effectively prevent and treat wooly aphis and two kinds of insects of yellow aphids with composition pesticide a drug of the present invention, the prevention and control effect is remarkable:
A, the experiment of the indoor virulence by a large amount of proportionings record: the composition pesticide that with Aphox and Acetamiprid is active ingredient reaches more than 230 the maximum co-toxicity coefficient of apple yellow aphid, and remarkable synergistic effect is arranged; About 100, the effect that is mixed symbolic animal of the birth year adds effect to the co-toxicity coefficient of wooly aphis.
The experimental data of b, table 1 and table 2 can illustrate the field effect of composition pesticide of the present invention to wooly aphis and two kinds of insects of yellow aphids:

2, there is action compensating in two active ingredients of composition pesticide of the present invention when two kinds of aphids of prevention and control, respectively get the chief, rational proportion by screening synergy or summation action, overcome the shortcoming that exists separately, the pest natural enemy safety is improved, compare with the method for present control, not only help lowering the control cost, and more help sustainable Control of insect and the integrated control system of optimization insect.
3, not only the prevention and control effect to apple yellow aphid and woolly aphid is remarkable for composition pesticide of the present invention, and the various aphid evils that take place on the crops such as other fruit tree, vegetables, flowers and grain are also had good control efficiency.
