Description
Technical field
The invention belongs to technical field of pesticide more particularly to a kind of composition pesticide, slow releasing medicinal fertilizer and preparation method thereof.
Background technology
Wheat aphid is a kind of pest that the long-term occurring area of wheat is maximum, harm is most heavy, is the important pests of China's wheat
One of, species mainly includes three kinds of grain aphid, green bugs and rhopalosiphum padi.Wheat aphid individual is small, and breeding is fast, in wheat
Entire breeding time can all occur and one of the primary pest of Wheat During Later Period of Growth, inhales harm into assassinating to wheat, influences wheat
Photosynthesis and nutrient absorption, conduction endanger blade, stalk and tender fringe, especially after wheat heading, temperature rise, and aphid
Reproduction speed is accelerated, and concentrates on fringe portion harm, forms blighted grain, if prevention is not in time, causes mass of 1000 kernel degradation, generally subtract
Production 10%~30%.Nymph, adult Chang great Liang are clustered in blade, stalk, fringe portion and draw juice, are in just yellow stigma by harm,
It is afterwards streak, withered, whole strain change is withered till death, and loss is very big.Aphid not only causes directly to endanger, and also propagates wheat virus disease, such as
Yellow stunt of wheat etc..Weather gradual warmed up in recent years, and wheat aphid is very urgent to the prevention of aphid in ascendant trend year by year.
At present, to the prevention of aphid, there is situations partially early or too late.See worm i.e. dispenser, spray number accordingly increases,
It causes to prevent that cost is excessively high, while the aphid resistance to the action of a drug is caused to enhance, further increase difficulty of prevention and cure；Too late, aphid is then for prevention
Through causing certain harm to wheat, aphid density is excessive, such as cannot uniform dispenser, it is impossible to the effectively harm of control aphid.
And most of peasant households anti-specific aim when selecting medicament, is mistakenly considered the high agricultural insecticide effect of toxicity relatively
It is good.High poison and poisoning class pesticide be generally broad spectrum insecticide, effectively prevention target pest while, can also injure natural enemy and
Some beneficial organism species such as honeybees etc., and then the balance of the ecosystem in entire farmland is destroyed, to people and animals, water body, ecological ring
Border pollutes.Meanwhile lasting period section, the residual of high-toxic pesticide are high, closing on harvest time dispenser can cause grain pesticide residue to surpass
Mark is unfavorable for the healthy living of the people.
The content of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of composition pesticide, slow releasing medicinal fertilizer and its system

Description of the drawings
Fig. 1 is the production technological process of slow releasing medicinal of the present invention fertilizer.
Specific embodiment
Below in conjunction with the attached drawing of the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained without making creative work
Example is applied, belongs to the scope of protection of the invention.
The present invention provides a kind of composition pesticide, including Diacloden, amino-oligosaccharide and humic acid；The Diacloden,
The mass ratio of amino-oligosaccharide and humic acid is preferably (0.01~2)：(0.1~1)：(0.1~5), more preferably (0.02~
1.5)：(0.1~1)：(0.2~4) is further preferably (0.02~1.5)：(0.1~1)：(1~3).
In some embodiments provided by the invention, the mass ratio of Diacloden, amino-oligosaccharide and humic acid is 1:5:10.
In some embodiments provided by the invention, the mass ratio of Diacloden, amino-oligosaccharide and humic acid is 1:2:10.
In some embodiments provided by the invention, the mass ratio of Diacloden, amino-oligosaccharide and humic acid is 1:1:5.
In some embodiments provided by the invention, the mass ratio of Diacloden, amino-oligosaccharide and humic acid is 5:8:10.
In other embodiments provided by the invention, the mass ratio of Diacloden, amino-oligosaccharide and humic acid is 1:1:
3。
Diacloden, English common name (Thiamethoxam), chemical name 3- (the chloro- 1,3-thiazoles -5- ylmethyls of 2-) -5-
Methyl-1,3,5- oxadiazines -4- bases fork (nitro) amine, belongs to nicotinic insecticide, the mechanism of action is mainly selective depression
Insect CNS nicotinic acetylcholine esterase receptor, and then the normal conduction of insect CNS is blocked, it causes
Pest occurs dead during paralysis machine.Diacloden not only have tag, stomach toxicity, systemic activity, but also with higher activity, more preferable
Security, wider array of insecticidal spectrum and work fast, the features such as lasting period is long, be substitution those are high to mammalian toxicity,
There are the organophosphor, carbamate, the preferable kind of organochlorine insecticides of residual and environmental problem.Meanwhile Diacloden is to sheath
Wing mesh, Diptera, Lepidoptera, especially homoptera pest have high activity, can effectively prevent various aphids, leafhopper, plant hopper, powder
The pests such as lice, chafer larva, colorado potato bug, nematode, ground beetle, leaf miner and polytype chemical pesticide generate resistance
Pest.Diacloden and imidacloprid, Acetamiprid, Nitenpyram no interactions resistance.Can be not only used for cauline leaf process, seed treatment,
Available for soil treatment.Under recommended dose use to crop safety, without poisoning.
Amino-oligosaccharide, be microbial metabolism extraction a kind of fungicide with resistant effect, the life to some germs
With inhibitory action, fungus spore germination is such as influenced, hypha form is induced and morphs, the intracellular biochemical reaction of mycelia becomes
Change etc., the mechanism that induction plant generates disease resistance are mainly to excite gene expression in plants, chitinase of the generation with antibacterial action,
Dextranase protects element and PR albumen etc., while has the gene expression for inhibiting germ, and the Physiology and biochemistry of mycelia is made to morph,
Growth is suppressed, while can also stimulating growth.
Humic acid is that a series of transition process of the remains of animals and plants through microorganism decomposition and conversion and natures is formed
A kind of organic substance, be widely present in nature, soil, waters, coal, shale and earth's surface have its presence.It is rotten
Phytic acid can play pesticide sustained-release synergistic, slow down decomposition, the effect reduce toxicity, extend drug effect, reducing dosage.
Amino-oligosaccharide, humic acid Diacloden are used in mixed way by composition pesticide of the present invention, and toxicity is all higher than 120, tool
There is notable synergy, and the composition pesticide has preferable preventive effect to wheat aphid.Amino-oligosaccharide can induce plant
Object resistance promotes plant POD, SOD, PAL activity to improve, promotes induction biosynthesis protective plant protecting agent, excite plant lignin synthesis and
Accumulation improves crop resistance, promotes plant growth.Humic acid can play pesticide sustained-release synergistic, slow down decomposition, reduce poison
Property, extend drug effect effect.
