Abstract
The present invention relates to a multi-effect flowable concentrate for seed coating, which comprises the effective ingredients of thiamethoxam and fludioxonil. The multi-effect flowable concentrate for seed coating of the present invention contains 1-55% of thiamethoxam, preferably 5-40%, and 1-65% of fludioxonil, preferably 5-40%. The multi-effect flowable concentrate for seed coating of the present invention can be used for seed coating, has characteristics of long duration, low toxicity and remarkable synergism, and can be applied to control of soil insects such as grub, mole cricket and wireworm in peanut, corn, wheat and rice, and control of insects with sucking mouth part, such as seedling aphide, brown planthopper, thrips, powdery mildew and leafhopper, and control of diseases of fusarium wilt, banded sclerotial blight, full rot, rice blast, powdery mildew and bacterial wilt.
Description
Technical field:
The present invention relates to a kind of suspension seed-coating agent and preparation method thereof, its active ingredient is thiophene worm piperazine and fludioxonil.
Background technology:
Thiophene worm piperazine, English name are Thiamethoxam, and its chemical name is: 3-(2-chloro-1,3-thiazoles-5-ylmethyl)-5-methyl isophthalic acid, 3,5-oxadiazines-4-base fork (nitro) amine.Be a kind of second generation anabasine high-efficient low toxicity insecticide of brand new, insect is had tag, stomach toxicity and systemic action, can be used for page spraying and irritate the root processing with soil.Thiophene worm piperazine has splendid interior suction conductivity, rapidly by interior suction, and conducts to each position of crop after the dispenser, for insects such as sucking pest such as aphid, plant hopper, aleyrodid, leafhopper good preventive effect is arranged.
Because it has fabulous interior absorption and conductivity, be to make kind of the good selection of clothing agent.
Fludioxonil, chemical name is: 4-(2,2-two fluoro-1,3-benzo dioxy-4-yl) pyrroles-3-nitrile.Its mechanism of action does, through suppressing the relevant transfer of glucose phosphorylated, and suppresses the growth of fungal mycelium, finally causes germ dead.The mechanism of action is unique, does not have cross resistance with existing bactericide.
Fludioxonil derives from the natural products pyrrolnitrin, new pyrrole class, non-internal-absorting, wide-spectrum bactericide.Be mainly used in wheat, barley, corn, pea, rape, paddy rice, ornamental crops, xylocarp, vegetables, grape and lawn etc.Using dosage is 250～500g (a.i.)/ha.Be used for the rotten sickle spore bacterium of control snow, wheat net raw meat black rot, rhizoctonia solani etc. as the blade face bactericide, gray mold is had special efficacy; As seed treatment, be mainly used in and prevent and treat the disease that kind of biography and soil-borne disease bacterium such as Alternaria, Ascochyta, aspergillus, Fusarium, Helminthosporium, Rhizoctonia and Penicillium bacterium etc. cause in cereal and the non-cereals crop.
Two kinds of medicaments are if use as kind of clothing agent separately, and its property of medicine is single, and can not reach holds concurrently imitates double controlling.And two kinds of composite reagents then can reduce dispenser cost savings resource as kind of a clothing agent, and reaching holds concurrently imitates the double effect of controlling.
Summary of the invention:
In order to overcome the above problems, the present invention proposes a kind of suspension seed-coating agent that contains thiophene worm piperazine and fludioxonil and preparation method thereof, purpose is that thiophene worm piperazine and fludioxonil carry out composite its advantage of giving full play to.
Content of effective is among the present invention: thiophene worm piperazine 1-55%, fludioxonil 1-65%; Preferably than being thiophene worm piperazine 5-40%, fludioxonil 5-40%.
Active ingredient thiophene worm piperazine and the fludioxonil total content mass ratio in preparation is 1-80% among the present invention, preferably than being 10-50%.
The prescription of the suspension seed-coating agent that the present invention relates to is:
The preparation method of this kind clothing agent is: take by weighing each raw material by above proportioning; Heat water to 50 ℃ then; Film forming agent and warning colouration are stirred adding, and solvent becomes film forming solvent fully, again active ingredient, emulsifier, dispersant, antifreezing agent, thickener etc. is dropped into ball mill grinding 2-5 hour; Make particle diameter all below 5 μ m, can make.
The kind clothing agent that the present invention relates to is a composite insecticidal bactericide, this kind clothing thinner stable in properties, and 54 ± 2 ℃ of condition lower seals were stored after 14 days; Heat storage resolution ratio is less than 5%, and suspensibility reaches international for kind of the regulation of clothing agent more than 90%; Through adding special film forming agent; Be used for seed pelleting, it is long to have a lasting period, safety and low toxicity, synergy outstanding feature.Can be used to prevent and treat soil insect such as grub, mole cricket, wireworm of crops such as peanut, corn, wheat, paddy rice etc.; Suckings pest such as control aphid in seedling stage, small brown rice planthopper, thrips, powdery mildew, leafhopper; Prevent and treat diseases such as fusarium wilt, banded sclerotial blight, full rot, rice blast, powdery mildew, bacterial wilt.
