Abstract
The present invention relates to an agricultural sterilizing composition aiming at plant pathogenic fungi and Pythiumspp. The agricultural sterilizing composition comprises the components by the following weight percentage: 1 to 15% of hymexazol, 15 to 40% of copper acetate, 1 to 15% of auxiliary agent and 30 to 83% of filling agent. The composition can be used for preventing and curing Pythium root rot of vegetables of garlic, ginger, onion, etc., and significant effect is obtained.
Description
Technical field
The invention belongs to pesticide field, relate to a kind of microbicide compositions.
Background technology
Along with the minimizing of per capita area of cultivated farmland and the change of cropping system, the crops continuous cropping is more and more general.The direct result that causes thus is the big generation of plant soil-borne diseases.By sprout term disease and the basal part of stem disease that plant pathogenic fungi-pythium spp causes, all cause every year the large-area seedling of ruining to turn over kind, suffer heavy losses.As recurrent pythium spp root rot on garlic, ginger, round onions in recent years, vegetables are produced threaten greatly.Domestic existing preparation cost height at pythium spp, fungicidal spectrum is narrow, control efficiency is undesirable.
Summary of the invention
The bactericide agricultural chemicals that the purpose of this invention is to provide vegetable crop pythium spp root rot such as a kind of efficient, economic control garlic, ginger, round onions.
Microbicide compositions provided by the invention is to be active ingredient to dislike mould spirit and Schweinfurt green, adds suitable adjuvants and filler, the wetting powder that processes through certain production technology.
(chemical name: being a kind of systemic fungicide 3-hydroxy-5-methyl base isoxazole), is again a kind of soil disinfectant to dislike mould spirit.The registered control that is used for diseases such as paddy rice and black leg of beet.Schweinfurt green mainly plays the prevention protective effect, and antimicrobial spectrum is wide, but result of treatment is relatively poor.Inventor's test of many times shows, dislike mould spirit and Schweinfurt green composite by a certain percentage after, can produce obvious synergistic effect.Disliking the composite by a certain percentage co-toxicity coefficient to the ginger pythium spp of mould spirit and Schweinfurt green is 209.6, and virulence regression equation is Y=2.0263+1.7452x, and synergistic effect is remarkable.Field trial shows, composition provided by the invention is converted the effect that water is made into 600 times of soups control ginger pythium spp root rot and reached 90%.The synergy of said components is described, bactericidal activity of the present invention is obviously improved.
Dislike mould spirit and Schweinfurt green composite after, control spectrum enlarges.This composition also has good control efficiency to diseases such as garlic, round onions pythium spp root rot.For example these composite dose of 500 times of liquid reaches 88% to the field efficacy of garlic pythium spp root rot, and the field efficacy of round onions pythium spp root rot is reached 86%.The composite of mould spirit and Schweinfurt green disliked in this explanation, and not only synergy is obvious, and has enlarged fungicidal spectrum, and prevention and treatment range obviously enlarges.
Disliking mould spirit and Schweinfurt green composite by a certain percentage is one of important technology feature of the present invention.
Another important technology feature of the present invention is that composition is a wetting powder.
The preferred composition proportion of this composition is:
Composition percentage by weight (%)
Dislike mould clever 1～15
Schweinfurt green 15～40
Auxiliary agent 1～15
Filler 30～83
The optimal components proportioning is:
Composition percentage by weight (%)
Dislike mould clever 5～12
Schweinfurt green 25～35
Auxiliary agent 5～10
Filler 43～65
Production technology of the present invention is: will dislike mould spirit, Schweinfurt green, auxiliary agent and filler in mixing in the predetermined ratio adding mixer, first precomminution is pulverized, is sieved, and packs through after the assay was approved and promptly gets product.
Using method of the present invention is: convert the water mixing by a certain percentage, be made into blade face or basal part of stem spraying behind the soup, the field working concentration is 500～1000 times.Perhaps with fine sand or the ditch spread of fine earth mixing or spread manuer in holes.Usage amount is per 1000 gram garlic kind dosages, 2 grams during the garlic seed dressing.
Vegetables pythium spp root rot such as 400～1000 times of controls of dilute with water of the present invention garlic, ginger, round onions can obtain good effect.
Advantage of the present invention:
1. synergistic effect is remarkable, the field efficacy height.When using multiple to be 600 times, the effect of the mould root rot of the rotten bacterium of ginger is reached 90%.
2. fungicidal spectrum is wide, has reduced expenses for prevention and control.Because disease big polyhybird in field takes place, use this compositional bactericidal agent for preventing and treating Zhiduo County of once holding concurrently and plant disease.This has not only reduced the control cost, has also saved vegetable grower's labour.
3. cost of material is low, and production technology is simple.
Embodiment
Below the invention will be further described with embodiment.
Embodiment 1:
Composition percentage by weight (%)
Dislike mould clever 7
Schweinfurt green 33
Auxiliary agent 7
Filler 53
Embodiment 2:
Composition percentage by weight (%)
Dislike mould clever 10
Schweinfurt green 30
Auxiliary agent 10
Filler 50
The described composition of above embodiment is converted water and is made into 700 times of liquid irrigating roots, and the field control effect of ginger pythium spp root rot is all reached more than 85%.
