Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, active ingredient is glyoxalin, and formulation is water dispersible granules and preparation method thereof.Be mainly used in the control of citrus scab, anthracnose of grape, pear scab.
Background technology
At present; disinfectant use in agriculture is a lot; glyoxalin is wherein a kind of; belong to azole broad-spectrum foliage systemic fungicide, have protection and treatment double action, the main mechanism of action is to destroy and stop the biosynthesis of the cell membrane important composition composition ergosterol of germ; thereby destroy the formation of cell membrane; cause germ death, can rapid osmotic after the spraying in plant corpus, resistance of rainwater washing against.It is mainly used in the fungal disease of control crop, safety is good, fungicidal spectrum is wide, remarkably productive, be one of product that effect better in the control of present fungal disease, activity is higher, consumption is less.But the former powder of glyoxalin in the market, the wetting powder that has been made generally in low content uses, and wetting powder is serious in preparation and use dust pollution, human and environment all there is very big harm, shortcomings such as effective rate of utilization is low, and the lasting period is short are a lot, and are that agricultural chemicals development intermediate frequency faces superseded formulation, the fortune storage is inconvenient, is difficult for packing, use cost height.Water dispersible granules not instrument has reduced peasant's use cost, and has reduced the pollution to environment, and the present invention in use has content height, fast, the good dispersion of disintegration, is beneficial to the advantage of storing and stability, and activity is high, usefulness is good, safety.
Citrus scab: be a kind of by the microbial fungal disease of citrus scab, this pathogen only endangers citrus.This disease only infects the tender tissue of susceptible variety, as young fruit and spire.Produce water stain shape, yellowish-brown projection point during the spire morbidity earlier, suberification immediately and protuberance present convex lens shape or coniform, and color also becomes dead color, grey or brown by bright look.Produce water stain shape, brown projection point during the young fruit morbidity earlier, after become coniform, mamillary or excipuliform, the top suberification of protuberance, scab is brown or canescence, rough surface, leaf malformation distortion when serious, fruit is little, lopsided, normal early fallout, fruit juice is few and flavor acid causes the oranges and tangerines underproduction and low quality.
Anthracnose of grape: be a kind of disease that early takes place in the annual vineyard, mainly infect the tender tissue of plant, the grape children can both fall ill at tender positions such as blade, petiole, fruit, carpopodium, cob, tendril and young sprout.Begin to occur pinhead-sized bronzing spot after the blade morbidity, yellow haloing is arranged on every side, later scab enlarges rounded or irregular shape, and central authorities become canescence, depression slightly, the edge crineous, and take place along the vein consecutive.After vein is injured,, often make leaf curling, shrinkage because tissue is withered, in addition withered.Produce the crineous depression scab of oblong or bar shaped, later middle body becomes taupe, and the above branch in serious susceptible position is withered.Produce circular dark brown point at the beginning of the fruit morbidity, enlarge later on, diameter can reach 2～5 millimeters, and medial recess is canescence, and outside dark brown, periphery have purple brown tinge, presents typical " bird's eye " scab.The young fruit of catching an illness is childlike, and color depth is green, and the sour matter of distinguishing the flavor of is hard, lopsided, and the scab place ftractures sometimes.
Pear scab: be a kind of quarantine venereal disease evil, mainly directly invade the people from plant leaf blade, fruit, the climing epidermis of stem, also can invade from pore and wound, disease portion begins depression to occur, is the silly shape of dun sore, and flows out translucent jelly, then become amber, diseased tissues stops growing, bending, and when not deliquescing, without putrefaction, high humidity, sick portion produces the mould layer of black.
Summary of the invention
The objective of the invention is to improve a content height, dosage is little, and is satisfactory for result, the efficient height, active ingredient usage amount height, the filler usage amount is little, environmental pollution is little, uses easily, and use cost is low, the safety coefficient height, pollution-free to the crop blade face, can promote the photosynthesis of crop, packing is simple, storing is convenient, during use human body is not had the science environmental protection formulation of injury.Another purpose is to be prepared into outstanding formulation and easy to use, the high high-content water-dispersion granula of practical efficiency.
Technical scheme among the present invention and such realization, its composition of a kind of Imibenconazole water dispersible granule comprises: glyoxalin 80-800 part, wetting agent 20-40 part, dispersant 20-40 part, disintegrant 20-80 part, adsorbent 10-30 part, adhesive agent 10-50 part, stabilizing agent 10-40 part, filler 50-500 part.Wherein, the required auxiliary agent type of agent is found in aqueous dispersion according to claim 1, prepares according to the product concrete condition.
Owing to add the auxiliary agent of heterogeneity, make active quantities height of the present invention among the present invention, pollutes little, availability height, convenient, the stable easily use of storing.Have also that disintegration rate is fast, the advantage of good dispersion, good fluidity.
