Abstract
The invention relates to agricultural chemistry, in particular to a polypharmaceutical for preventing and controlling plant diseases and insect pests of the seedling stage of cotton. The polypharmaceutical is characterized in that the polypharmaceutical consists of active constituents such as hymexazol, ruisheng, humic acid, a synergistic agent, an adhesive and so on, and a supporting auxiliary agent system, and is a suspended liquid which has a pesticide-fertilizer compounding type and is produced by processing technologies such as wet crushing, ultrafine grinding and so on. Concrete components in percentage by weight are 30 percent of ruisheng, 40 percent of bochemistry favic aid, 20 percent of hymexazol, 1.2 percent of novel strong permeability cinnamyl ketone or laurocapam, and 8 percent of cotton seed oil or soybean oil. Through control experiments to the plant diseases and insect pests of the seedling stage of the cotton, the control effect of the product is 95 percent or so, and the product has the effect of increasing more than 26 percent of yield, has pesticide effect, and also has fertilizer effect.
Description
Technical field
The present invention relates to agrochemistry, particularly a kind of combination drug of preventing and treating diseases and pests in cotton seedling.
Background technology
Owing to influenced by geological conditions, planting habit, Cotton in China continuous cropping phenomenon is more serious, the phenomenon of continuous cropping 4--6 is very general, the plot that has even reach about 10 years, and in recent years behind the sowing cotton seed cloudy day many, temperature is low, the normal growth that has a strong impact on cotton is grown, it is serious to cause diseases and pests in cotton seedling to take place, cotton seedling death.Cotton seedling lethality is about 1.20%, and the heavier time reaches more than 4%, reaches 12.40% than the important place piece, even has or not the phenomenon of emerging to take place.The damage by disease and insect of harm cotton in seedling stage mainly is cotton seedling blight, and Chang Yumian seedling anthracnose, red rot are mixed and sent out.Cardinal symptom: preceding as if suffering the germ infringement behind the sowing cotton seed to being unearthed, will cause the mashed bud of planting, rot, can not normally be unearthed.Cotton seedling after being unearthed also is subjected to the infringement of germ easily in first quarter moon, its symptom is the rhizome portion place existing yellowish-brown spot of cotton seedling near the soil table, after be strip brown depression, hanging shortens the wasp waist shape into, cotyledon withers vertical, the seedling lodging is withered.When rhizome portion was injured, it is fibrous that phloem rots to be dark brown.When sick seedling was extracted in soil, often there was the ped of the glutinous band of mycelia in sick portion.The route of transmission: the germ in the soil can will directly be infected cottonseed, seedling attached to surviving the winter in invalid body or the compost that does not become thoroughly decomposed fully.The germ mycelia that produces on the cotton seedling that is injured can continue to endanger contiguous strong seedling, enlarges and infects.Therefore, morbidity causes serious disconnected ridge, the cotton field phenomenon of being short of seedling often.Germ is run concurrently parasitic and saprophytic, but long-term surviving is in soil.Onset condition: conditions such as the generation of this disease and weather, soil are closely related, and low temperature, high humidity help the generation of damage by disease and insect, so behind sowing cotton seed, if meet low temperature overcast and rainy day, or the consecutive low temperature time is longer, when soil moisture was big, damage by disease and insect took place serious.If ground temperature rises or soil moisture reduces, this disease then stops development.
Mainly prevent and treat method at present: crop rotation, autumn ploughing winter irrigation, meticulous whole ground, select for use breeding to carry out the seed treatment proper seeding, will strengthen seedling management for the cotton field that damage by disease and insect takes place and reduce germ and encroach on cotton seedling and route of transmission, intertillage and loosen the soil and improve 1--3 ℃ of ground temperature, promote cotton shoot root system to grow to make its healthy and strong growth strengthen resistance against diseases.Measure influences enforcement because of carrying out plastic mulching but the restriction that crop rotation is ploughed, intertillage are loosened the soil.Medicament of the present invention mainly provides a kind of seed dressing medicament.
The present invention is through formulation screening test, determine that reagent combination forms by disliking mould spirit, sharp victory, humic acid, synergist, adhesive agent isoreactivity component and auxiliary aid system constructing, for medicine fertilizer compound, have the insect pest of integrated control cotton in seedling stage main diseases and regulate the effect that cotton seedling is grown, prescription is reasonable, and applicability is strong.
The present invention fills a prescription and can improve degeneration-resistant function of crop and immunity; harmful substance is got rid of in the degraded complexing; activate desirable genes; not only can supply with sufficient nutrient component; can also regulate the cotton physiology function, suppress the growth of cotton seedling blight, fusarium wilt cause of disease spore, can effectively protect cotton seedling to exempt from insects such as early stage aphid, thrips and cause harm; make cotton strengthen anti-adversity, thereby suppress the generation of diseases and pests in cotton seedling effectively.
Summary of the invention
Technical scheme of the present invention is to realize like this.A kind of combination drug of preventing and treating diseases and pests in cotton seedling, it is characterized in that forming by disliking mould spirit, sharp victory, humic acid, synergist, adhesive agent isoreactivity component and auxiliary aid system constructing, for medicine fertilizer compound, the suspension type liquid of producing through processing technologys such as waterproof pulverization and superfine grindings.Specifically be that composition and weight ratio are: sharp victory 30%, biochemical fulvic acid 40%, dislike mould clever 20%, novel osmanthus ketone or bay nitrogen humulone 1.2%, cottonseed oil or the soybean oil 8% of oozing by force.
By to the control of diseases and pests in cotton seedling test, this product control efficiency and has the effect of volume increase more than 26% about 95%, and existing drug effect has fertilizer efficiency again.
Embodiment
This product adopts and relies mainly on prevention, and seed dressing can reach control Rhizoctonia solani Kuhn, sickle-like bacteria before the sowing, and the blight germ is killed in the infringement of germs such as pythium spp.Concrete mode:
Seed dressing before the sowing: dress seed in pharmacopoeia ratio 1:60.
