Abstract
The invention belongs to the technical field of pesticide, and particularly discloses a compound preparation containing methyl sulcotrione and emamectin benzoate. The compound preparation containing methyl sulcotrione and emamectin benzoate comprises the effective ingredients of methyl sulcotrione and emamectin benzoate, wherein the weight ratio of the methyl sulcotrione to the emamectin benzoate is (5:1)-(50:1). The compound preparation containing methyl sulcotrione and emamectin benzoate has the beneficial effects that herbicide and insecticide are used after compounding, so that the functions of weeding and disinfesting are realized, the frequency and time of field operation are reduced, the cost is lowered, and the yield is improved. The compound preparation is safe and harmless to crops, degrades naturally in an environment without accumulation, is convenient and efficient to apply, is economical and practical, improves the economic benefit, and is mainly applied to controlling weeds and insect pests in a corn field.
Description
(1) technical field
The present invention relates to technical field of pesticide, particularly a kind of complex preparation that contains mesotrione and first dimension salt.
(2) background technology
It is logical that mesotrione has another name called the Meath, is characterized in environmentally friendly, can degrade widely fast, and final metabolite is carbonic acid gas.Corn is because corn is slow to the infiltration rate of medicament to the resistance of mesotrione; But corn can be degraded to mesotrione the compound of non-activity rapidly, particularly passes through the 4-hydroxylation of P450 catalysis.Mesotrione is mainly used in preventing and kill off corn field annual broadleaf weed and grassy weed, and lamb's-quarters, amaranth, Tong fiber crops, Siberian cocklebur, lady's-grass, green foxtail etc. are had the better prevention effect, and the activity of weeding height to corn safety, has application prospect comparatively widely.
First dimension salt full name emamectin-benzoate, it is a kind of new and effective semisynthetic antibiotics insecticide that begins to synthesize from fermented product Avermectin B1, it has the characteristics of super-high-efficient, low toxicity (preparation is closely nontoxic), low-residual, biopesticide such as nuisanceless, existing stomach poison function is double action of contace poison again, under low-down dosage, has good effect, and in the process of pest control, beneficial insect is not injured, be conducive to the integrated control to insect, reduced the toxicity to people and animals.
Corn is important cereal crops and the main feed of China always, and plantation distributes and spreads all over the whole nation, and the weeds between corn field and insect have a strong impact on its quality and output.Weed killer herbicide mesotrione and insecticide first dimension salt often uses as preparation separately at present, can not desinsection in weeding, can not weed eradication in desinsection, strengthened number of times and the time of farm work, increase dispenser cost and labour, also be unfavorable for the raising of corn yield simultaneously.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, provide a kind of desinsection and herbicidal effect significantly, the farm work number of times is few, use cost is low, corn yield is high, prevent and delay pest resistance to insecticide development, environment is had the complex preparation that contains mesotrione and first dimension salt of compatibility preferably.
The present invention is achieved through the following technical solutions:
A kind of complex preparation that contains mesotrione and first dimension salt, its active ingredient consists of mesotrione and first dimension salt, and the weight ratio of described mesotrione and first dimension salt is 5: 1-50: 1.
This contains the complex preparation of mesotrione and first dimension salt, and its preferred scheme is that the weight ratio of mesotrione and first dimension salt is 9: 1-39: 1.
This contains the complex preparation of mesotrione and first dimension salt, and its active ingredient mesotrione and first dimension salt account for the 10%-60% of complex preparation gross weight, and all the other are auxiliary element.Described auxiliary element can be dispersant, emulsifier, wetting agent, stabilizing agent, thickener, defoamer, filler or adhesive, and reaching other is of value to active ingredient stable material of bringing into play with drug effect in preparation, can be wherein one or more.This auxiliary element is conducive to that complex preparation is made suitable agricultural and goes up the formulation of using, and preferred formulation is wetting powder, water dispersible granules, oil suspending agent or aqueous suspension.
Described dispersant is one or more in lignin and derivative sulfonate, naphthalene and alkylnaphthalene sulfonate formaldehyde condensation products, polycarboxylate salt dispersant, the alkylphenol polyoxyethylene phosphate.
