Abstract
The invention relates to an acaricide composition prepared by using pyrimidifen and etoxazole as main ingredients and adding emulsifier as well as organic solvent. The composition has the advantages of special effects on preventing and eliminating mite and ovum thereof, larva and nymphae, simple processing technique, no three wastes and convenient use.
Description
(1) technical field
The invention belongs to pesticide field, relate to a kind of acaricide composition.
(2) background technology
The evil mite cereal crops such as fruit, vegetables, tea tree, fruit tree, ornamental plants, soybean of can causing harm, in recent years because the variation of field ecosystem and the enhancing of evil mite pesticide resistance, it is caused harm the trend of increasing the weight of, big continuously throughout the country the generation, various vegetables and cereal crops are caused very big loss, become important pest.
Although it is various in style to be used to prevent and treat the miticide of harmful mite at present, but it is always unsatisfactory, as 1000 times of liquid of 20% Dicofol emulsion, 800 times of liquid of 73% propargite missible oil, 1500 times of liquid of 50% Bristol wetting powder, 800 times of liquid of 35% zolone, 3000 times of liquid of 5% hexythiazox missible oil, 2000 times of liquid of 25% times of happy despot's wetting powder, 600～800 times of liquid in 50% malathion, 2000 times of liquid of 25% fenvalerate missible oil etc., the control worm attitude that has is single, the cost height that has, the residual height that has.
(3) summary of the invention
The purpose of this invention is to provide a kind of efficient, low toxicity, miticide agricultural chemicals safe in utilization.
A kind of acaricide composition provided by the invention is the missible oil that is processed through certain production technology by pyrimidifen, second mite azoles, emulsifier and organic solvent.
The pyrimidifen chemical constitution is as follows:
Be a kind of new high-efficiency miazines miticide, be mainly used in the evil mites such as tetranychid of all vegetative stages such as control fruit tree, vegetables, tea, the diamond-back moth on the vegetables is also had good active, using dosage 25～75g (a.i.)/hm
2Pure product pyrimidifen is a clear crystal, m.p.69.4～70.9 ℃, dissolubility (20 ℃, g/l): water 0.000217.The former medicine acute LD 50 of pyrimidifen (mg/kg): rat oral 148 (hero), 115 (female), its mouse oral 245 (hero), 229 (female), rat is through skin〉2000.When using the agent of pyrimidifen list, better to evil mite adult control efficiency, but easily develop immunity to drugs.
Second mite azoles chemical constitution is as follows:
Be a kind of new high-efficiency Xing oxazoline class miticide of tagging, belong to mite and the aphid inhibitor of casting off a skin, the ovum, larva and the nymph that are mainly used in multiple mites such as control fruit, vegetables, tea, fruit tree have tall and erect the effect, to becoming mite invalid, and using dosage 50～100g (a.i.)/hm
2Pure product second mite azoles is a white powder, m.p.101～102 ℃, dissolubility (20 ℃, g/l): methyl alcohol 90, ethanol 90, acetone 300, cyclohexanone 500, ethyl acetate 250, dimethylbenzene 250, n-hexane 13, acetonitrile 80, oxolane 750.The former medicine acute LD 50 of second mite azoles (mg/kg): large and small mouse per os〉5000, rat is through skin〉2000; To lagophthalmos eyeball and skin nonirritant; Animal there are not teratogenesis, mutagenesis, carcinogenesis.
The inventor measures through test of many times, pyrimidifen and second mite azoles are composite by a certain percentage, under the emulsifier effect, 24 hours co-toxicity coefficients to the evil mite are 201.73 after the dispenser, virulence regression equation is y=3.719+2.425x, a large number of experiments show that insecticides provided by the invention is (every 666.7m under recommended dose
2Consumption 33.3 grams～50.0 grams), 24 hours field control effects to evil mite adult are 85%～97% after the dispenser, and ovum, larva and the nymph of evil mite all had good control efficiency.Emulsifier is necessary auxiliary agent, and organic solvent is a carrier.
Pyrimidifen and second mite azoles are composite according to a certain percentage to be one of key character of the present invention.
Preferred proportioning components is:
Composition percentage by weight (%)
Pyrimidifen 5.0～15.0
Second mite azoles 10.0～20.0
Organic solvent 30.0～70.0
Emulsifier 6.0～10.0
Best proportioning is:
Composition percentage by weight (%)
Pyrimidifen 8.0～10.0
Second mite azoles 12.0～18.0
Organic solvent 60.0～70.0
Emulsifier 6.0～10.0
Production technology of the present invention: pyrimidifen and second mite azoles under stirring condition, are used organic solvent dissolution, add emulsifier and organic solvent in proportion, after fully stirring, leave standstill, after being up to the standards on request packing be product.
The present invention is used to prevent and treat harmful mite and ovum, larva and nymph can be obtained good effect.
Advantage of the present invention is:
1. efficient, low toxicity, preparation is recommending consumption control evil mite and ovum, larva and nymph effect to reach 85%～97%.
2. technology is simple, and the raw material of input all is converted into product, yield height, the no three wastes.
(4) embodiment
Below the invention will be further described with embodiment:
Composition percentage by weight (%)
Pyrimidifen 9.0
Second mite azoles 15.0
Emulsifier 10.0
Organic solvent 66.0
Claims (4)
1. an acaricide composition is characterized in that with pyrimidifen and second mite azoles be Main Ingredients and Appearance, adds emulsifier, organic solvent is formulated.
2. acaricide composition according to claim 1 is characterized in that its composition and percentage by weight are as follows:
Composition percentage by weight (%)
Pyrimidifen 5.0～15.0
Second mite azoles 10.0～20.0
Organic solvent 55.0～75.0
Emulsifier 6.0～10.0
3. acaricide composition according to claim 1 is characterized in that the part by weight between pyrimidifen and the second mite azoles is 80:(100～150).
4. acaricide composition according to claim 1 is characterized in that said composition is used to prevent and treat harmful mite and ovum, larva and nymph.
