Abstract

The invention is a high-effectivity, low-poison compounded pesticide, made by mixing orthene, triazole phosphorus and DDVP with an appropriate amount of solvent and the emulsifying agent respectively, the components including fipronil, wt% 1-5%. It can compound the fipronil, wt% 1-5% with the orthene 10-30%, or with the triazophos 5-20%, or with the DDVP 10-30% to compose these high-effectivity low-poison compounded pesticides. Compared with a common pesticide, it has obvious advantages of high effectivity, low poison, broad spectrum, etc. It can kill above two main pests for one time.

Description

Efficiently, compound pesticide of low toxicity

Technical field: the present invention relates to a kind of agricultural chemicals, particularly efficient, compound pesticide of low toxicity.

Background technology: striped rice borer, rice leaf roller are the primary pests of harm China Rice Production, and the conventional dose that is used in these insects of control at present in a large number has: 50% acephatemet missible oil, 18% dimehypo water solution, 90% desinsection list soluble powder, 20% triazophos emulsifiable solution etc.There are some drawbacks in these medicaments, have plenty of high malicious product, punish severely the quality that has influenced crops; After having plenty of this product of long-term use, make insect produce the pesticide resistance of punishing severely; Have plenty of the high residue product, the destruction of punishing severely human earth environment of depending on for existence.Therefore, the substitute products of efficient, the low toxicity of domestic urgent need exploitation, low-residual.

Summary of the invention: the object of the present invention is to provide a kind of efficient, low toxicity, low-residual, the insecticide of minimizing environmental pollution overcomes the above-mentioned drawback that has insecticide now.Technical solution of the present invention is a kind of efficient, compound pesticide of low toxicity, is made up of with an amount of solvent and emulsifier respectively orthene, Hostathion, dichlorvos, it is characterized in that including in its composition the fluorine worm nitrile that weight ratio is 1-5%.

Embodiment:

The present invention further specifies as follows in conjunction with specific embodiments:

1. 1 kinds of embodiment are efficient, compound pesticide of low toxicity, are 1-5% fluorine worm nitrile and the 10-30% orthene is composite forms by weight content ratio.

Embodiment 2. 1 kinds of efficient, low toxic pesticides are that 1-5% fluorine worm nitrile and 5-20% Triazoxide as built-up are formed by weight content ratio.

3. 1 kinds of embodiment are efficient, low toxic pesticides, are 1-5% fluorine worm nitrile and 10-30% is atgard mixed forms by weight content ratio.

Above-mentioned three kinds of formulations efficient, compound pesticide of low toxicity all can be missible oil or suspending agent or soluble powder or wetting powder or granule.

The present invention is efficient, the compound pesticide of low toxicity advantage is as follows: the insecticide composite with 1-5% fluorine worm nitrile and 10-30% orthene is example

1, efficient, low toxicity, low-residual, wide spectrum have a extensive future

In the development process, a large amount of control test effects confirm: removing control rice-stem borer, paddy stem borer, its preventive effect of rice leaf roller up to more than 98% by the composite fluorine worm nitrile orthene missible oil of above-mentioned weight ratio, is a kind of broad spectrum insecticide that the numerous species insect is all had outstanding preventive effect simultaneously.It all has high susceptibility to evils such as Lepidoptera, Semiptera, coleoptera, thripss and to the insect that chrysanthemum lipid, carbamates, cyclodiene develop immunity to drugs.Can be widely used in various crop insects such as control striped rice borer, paddy stem borer, rice leaf roller, locust, plant hopper, water weevil, thrips, diamond-back moth, cabbage caterpillar, liriomyza bryoniae, termite, and low toxicity, low-residual, be the first-selected insecticide of producing non-polluted farm product.

2, long-lasting, high activity, using dosage is low, the control cost is low

The biologically active of composite fluorine worm nitrile orthene missible oil is very high, so using dosage is low, and test shows, uses this product to prevent and treat most of lepidoptera pests, part Ji class pest; The paddy rice primary pest, required using dosages such as Plutella insect and colorado potato beetle are equivalent to the consumption of chrysanthemum ester class medicament, are the 1/15-1/5 of conventional dose usage amount.And under above-mentioned low dosage situation, the lasting period of this product is generally 2-6 week.Its control cost only is the 1/3-1/2 of chrysanthemum ester class and conventional dose series products, more than the control cost drop by half.

3, to the person poultry safety, to pest natural enemy and beneficial organism gentleness

In the composite fluorine worm nitrile orthene missible oil, there is the specificity of nerve cell receptors bind in main active ingredient fluorine worm nitrile between insect and mammal, make it more closely hinder the chloride channel of cold its nerve cell with the r-aminobutyric acid receptors bind of insect.Therefore, this product has good selection toxicity between vertebrate and insect.In addition, because the insecticidal activity height of this product, using dosage is low, therefore, to the person poultry safety, simultaneously to pest natural enemy, the beneficial organism influence is very little or do not have influence, shows stronger mild action.

4, synergistic effect is remarkable

The Toxicity Determination of carrying out through Hunan agricultural university confirms: is 1: 15 o'clock with fluorine worm nitrile and orthene by the ratio of active ingredient, and co-toxicity coefficient (CTC) is 164.4 under the LC50 level, is 159.6 under the LC90 level; The ratio of active ingredient is 1: 9 o'clock, and co-toxicity coefficient (CTC) is 174.6 under the LC50 level, is 172.8 under the LC90 level; The ratio of active ingredient is 1: 6 o'clock, and co-toxicity coefficient (CTC) is 154.6 under the LC50 level, is 156.8 under the LC90 level.All greater than 150, general insecticide co-toxicity coefficient value is 120 only to rice-stem borer CTC for three kinds of proportionings, and synergistic effect is remarkable, and wherein the ratio of active ingredient is 1: 9 o'clock the best, the synergistic effect maximum.

5, crop had the growth of promotion and production-increasing function

Process is to various crop evidences such as paddy rice, cotton, soybean, and composite fluorine worm nitrile orthene missible oil has hestening rooting, branch, tillers and increase the effect of leaf chlorophyll, thereby promotes crop yield to increase.

With the insecticide of 1-5% fluorine worm nitrile and 5-20% Triazoxide as built-up, or, good effect is arranged too with 1-5% fluorine worm nitrile and the atgard mixed insecticide of 10-30%.

In sum, the crops such as efficient, the compound pesticide of low toxicity of the present invention and present domestic paddy rice and cotton, vegetables Common insecticide is compared, and has the technical advantages such as significant efficient, low toxicity, wide spectrum. A drug can hold concurrently kill two kinds with On main insect, and the lasting period can be equivalent to above routine administration twice, and to the pest natural enemy gentleness, do not have mutual Resistance. Therefore, economize the worker, when economizing, economy, society and environmental benefit be all very remarkable, is to produce the green non-pollution farming The desirable pesticide of product.
