The invention utilizes the efficiency-increasing function between the active component of elliptone and rh-5849, and attains the aims of making up the shortcoming of single-dose agricultural chemical, overcoming the drug resistance of pests, improving the effect of the preparation, and enlarging the employing scope of the preparation.

Description

Rotenone and but food hydrazine mixed insecticide preparation

Technical field

The invention belongs to technical field of pesticide, be specifically related to a kind of rotenone and press down food hydrazine mixed insecticide preparation.

Background technology

Because the long-term single insecticide that uses a certain type that depends on, insect is easy to generate pesticide resistance, causes the dosage of chemical insecticide sharply to increase, and has not only increased production cost, and the natural enemy and the contaminated environment of a large amount of kill pests, cause the wildness harm of insect.

Rotenone is a kind of from the compound in plant derris root or the grey green soy bean blade, has good insecticidal activity, all effective to most of pest, consumption is low, very fast degraded in environment, not injuring natural enemy and other non-target organism, is a kind of outstanding biological insecticides, and its shortcoming is unstable.

The applicant's process lot of experiments expects rotenone and but after the food hydrazine reasonably was mixed, acquisition can overcome pest resistance to insecticide, expansion insecticidal spectrum, reduction consumption, the rotenone mixed insecticide with multiple formulation.

Summary of the invention

The objective of the invention is to fill up the blank of prior art, provide a kind of safe, efficiently rotenone with press down food hydrazine mixed insecticide preparation, eat rationally being mixed between the hydrazine by rotenone with pressing down, enlarge insecticidal spectrum, improve drug effect, reduce dosage, alleviate pollution environment.

Technical scheme of the present invention provides a kind of rotenone and presses down food hydrazine mixed insecticide preparation, by rotenone by weight 0.05～70%, press down the food hydrazine by weight 1～70% and the additive mixture of surplus form.

As preferred version of the present invention, described rotenone with press down food hydrazine mixed insecticide preparation by rotenone by weight 0.5%～50%, press down food hydrazine by weight 2～50%, all the other are auxiliary agent.。

Described rotenone can be one or more of the former medicine of rotenone, the plant extracts that contains rotenone or rotenone preparation, and when use was multiple, total usage amount can not be greater than the maximum of shared percentage by weight.

Described to press down the food hydrazine can be former medicine and/or preparation, using when multiple, and total usage amount can not be greater than the maximum of shared percentage by weight.

Described to press down the food hydrazine can be former medicine or preparation, using when multiple, and total usage amount can not be greater than the maximum of deal.

The invention has the beneficial effects as follows:

Rotenone with press down the food hydrazine and be mixed after, can overcome and press down the shortcoming that the food hydrazine is easy to generate resistance, can widen the scope of application of medicament, improve drug effect.Resistance management to insect has important effect.

Rotenone with press down the food hydrazine and be mixed after, not only kept numerous advantages of vegetable insecticide, and the dosage of mixture reduces, drug effect increases substantially, this mixture has great importance to the Application and Development of natural insecticide.

3. because the compatibility and the reasonable mixture ratio of required each material of this insecticides of preparation can greatly alleviate the toxic action to various pest natural enemies, little to the pollution of ecotope, help protecting the person poultry safety.

As can be seen from Table 2, rotenone is mixed with pressing down the food hydrazine, and co-toxicity coefficient is greater than 100, shows rotenone and presses down the food hydrazine and rationally be mixed and have synergistic effect.

Embodiment 14 rotenone and the effect experiment result who presses down food hydrazine mixed insecticide preparation:

Experiment one: with 18% rotenone with press down food hydrazine microemulsion, 2.5% rotenone emulsifiable solution and 20% and press down and after food hydrazine suspending agent dilutes 4000 times, 500 times, 1500 times respectively the diamond-back moth spraying is handled, investigation in the 1st, 3,7,14 day and calculate preventive effect after medication then.

4000 times of 20% rotenone with press down food hydrazine microemulsion to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 80.4%, 86.8%, 97.5%, 92.8%;

500 times of 2.5% rotenone emulsifiable solution to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 24.7%, 56.4%, 78.3%, 77.2%;

1500 times 20% press down food hydrazine suspending agent to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 51.7%, 70.5%, 87.3%, 77.4%.

Experiment two: with 3% rotenone with press down food hydrazine missible oil, 2.5% rotenone emulsifiable solution and 20% and press down and after food hydrazine suspending agent dilutes 1500 times, 500 times, 1500 times respectively the prodenia litura spraying is handled, investigation in the 1st, 3,7,14 day and calculate preventive effect after medication then.

1500 times of 3% rotenone with press down food hydrazine missible oil to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 76.4%, 85.2%, 95.4%, 91.8%; 500 times of 2.5% rotenone emulsifiable solution to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 25.6%, 46.3%, 68.1%, 74.1%; 1500 times 20% press down food hydrazine suspending agent to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 41.7%, 75.5%, 88.3%, 76.1%.

Contrast with former agricultural chemicals from the above-mentioned test of pesticide effectiveness explanation agricultural chemicals that the present invention was mixed, the control of insect is had remarkable control efficiency and synergistic effect and has the long lasting period.
