Abstract

The low-toxic quickly-acting insecticidal acaricide pesticide is mainly formed from (wt%) 0.5%-20% of acetamiprid and 2%-30% of other insecticidal acaricide. It possesses obvious synergized aztion, and can obtain good preventing and curing effect, does not produce resistance, and its duration of insecticidal and acaricidal action is long and its cost is low.

Description

Booth and greenhouse vegetable low toxicity quick-acting miticide pesticide

The present invention relates to a kind of agricultural chemicals, relate in particular to a kind of booth and greenhouse vegetable low toxicity quick-acting miticide pesticide that various pests such as tomato, cucumber, eggplant and legume crop trialeurodes vaporariorum, aphid, diamond-back moth, two spotted spider mite in booth and greenhouse evil mite is had favorable effect.

Along with the expansion year by year of protection ground cultivated area, the Trialeurodes vaporariorum Westwood distribution is extensive day by day, and the crop of planting in booth and the greenhouse is caused serious harm, and the annual economic loss that causes to peasant household is on average about 30%-50%.At this kind situation, though occurred a lot of pesticides on the agricultural chemicals market, but limitation has in various degree all appearred, cause very big difficulty for the control of trialeurodes vaporariorum, as " Buprofezin " is a kind of high selectivity insecticide, high to trialeurodes vaporariorum larva activity, but speed of action is extremely slow, strong as " Imidacloprid " interior absorption, trialeurodes vaporariorum is had greater activity, but because of its antibiosis strengthens, it is relatively poor that temperature is crossed low insecticidal effect, has the insecticidal activity height as " betacyfluthrin ", knock down fast, characteristics such as insecticidal spectrum is wide, and the lasting period is long, but absorption in not having, and toxicity is higher, as " Avermectin " is the insecticidal/acaricidal agent of succeeding in developing recently, and trialeurodes vaporariorum is had higher preventive effect, but because of its speed of action slow, cost an arm and a leg, comparatively difficult in agricultural extension.

The purpose of this invention is to provide a kind of effectively to insect control of pest mite such as booth and greenhouse vegetable trialeurodes vaporariorums, use cost is low, is difficult for producing the booth of resistance and greenhouse vegetable with low toxicity quick-acting miticide pesticide.

Technical scheme of the present invention realizes in the following manner:

Booth and greenhouse vegetable low toxicity quick-acting miticide pesticide, it mainly is missible oil or the wetting powder that contains Acetamiprid, other insecticidal/acaricidal agent, weight percentage is Acetamiprid 0.5%-20%, other insecticidal/acaricidal agent 2%-30%.

Other mite and insect killing agent is carbosulfan, pyridaben, efficient along anti-cypermethrin.

Missible oil formulation solvent is a dimethylbenzene.

Good effect of the present invention is:

1, synergistic effect is remarkable, and control efficiency obviously is better than producing going up uses insecticidal/acaricidal agent always.

2, be difficult for producing antibiosis, the lasting period is long.

3, use cost is low.

4, speed of action is fast.

5, toxicity is little, and consumption is little.

Below in conjunction with example formulations invention is described further:

Prescription 1: Acetamiprid 1%, carbosulfan 5%, emulsifier 10%, surplus is a dimethylbenzene.

Prescription 2: Acetamiprid 1%, carbosulfan 5% will mix with solid carrier behind the two component mixings, pulverizes.

Prescription 3: Acetamiprid 1%, pyridaben 5% behind both mixings, mixes pulverizing with solid carrier.

Prescription 4: Acetamiprid 1.5%, pyridaben 10%, emulsifier 8%, surplus is a dimethylbenzene.

Prescription 5: noisy worm amidine 0.5%, carbosulfan 19.5%, emulsifier 10%, surplus is a dimethylbenzene.

Prescription 6: Acetamiprid 1%, pyridaben 4.8%, emulsifier 11%, surplus is a dimethylbenzene.

Prescription 7: Acetamiprid 1%, efficient along anti-cypermethrin 2%, emulsifier 10%, surplus is a dimethylbenzene.

Claims

1, booth and the greenhouse vegetable quick-acting miticide pesticides of low toxicity, it is characterized in that: mainly contain the missible oil or the wetting powder of Acetamiprid, other insecticidal/acaricidal agent, important percentage composition is respectively 0.5%-20%, other insecticidal/acaricidal agent 2%-30%.

2, booth according to claim 1 and greenhouse vegetable is characterized in that with low toxicity quick-acting miticide pesticide other insecticidal/acaricidal agent is carbosulfan, pyridaben, efficient cis-, trans-cypermethrin.

3, according to described booth of claim 1-2 and greenhouse vegetable low toxicity quick-acting miticide pesticide, it is characterized in that missible oil formulation solvent is a dimethylbenzene.
