The present invention relates to a germicide composite which not only can be used for effectively controlling bacterial diseases, but also can be used for controlling fungal diseases of plants. Said germicide composite contains (by wt%) 1%-10% of zhongshengmycin, 5%-30% of bismerthiazol, 10%-45% of copper acetate, 1%-10% of adjuvant and 5%-83% of filling agent.

The invention provides a mixed herbicide containing propyrisulfuron, penoxsulam and bentazone and an application thereof. The mixed herbicide contains active components of the propyrisulfuron, the penoxsulam and the bentazone; the weight ratio of the propyrisulfuron to the penoxsulam to the bentazone is 1-40:1-20:1-100. The mixed herbicide provided by the invention can be used for controlling broadleaf weeds, gramineous weeds and nutgrass flatsedge.

The invention relates to an agricultural fungicidal composition for plant bacterial diseases. Each component and its weight percentage are respectively: thiacumazole 1-30%, copper acetate 5-40%, auxiliary agent 1-20%, filler 10-93%. For cucumber bacterial leaf blight, edge blight, zucchini soft rot, tomato canker, bacterial wilt, bacterial spot, pepper bacterial spot, watermelon bacterial angular spot and other vegetable bacterial diseases Prevention and treatment, the effect is remarkable.

The invention relates to the technical field of pesticide, and particularly relates to a biological fungicide composition. The biological fungicide composition contains zhongshengrnycin and kasugamycin, wherein the weight ratio of the zhongshengrnycin to the kasugamycin is 1: (0.2-7). The fungicide composition disclosed by the invention is significant in synergized action, high in field efficacy, and wide in bacteriocidal spectrum, and has good control effect on rice blast, fusarium wilt of cucumber, cucumber downy mildew, bacterial angular leaf spot of cucumber, tomato leaf mould, tomato bacterial macula diseases, pumpkin soft rot, watermelon bacterial angular spot, bacterial blotch of watermelon, stuffed watermelon water melon, pepper anthracnose, hot (sweet) pepper bacterial leaf spot, capsicum powdery mildew, pepper grey mould, citrus canker, litchi downy blight, peach tree gummosis, scab of peach and peach shot hole. The control cost is reduced.

The invention provides an acaricidal composition containing bifenazine, which also contains tannin; the mass ratio of the tannin and bifenazine is 10:1-1:10; the tannin and biphenyl The total content of hydrazine ester is 0.1‑99.9 wt%, and the rest are auxiliary materials. The acaricidal composition containing bifenazate of the present invention has good effects on various crop herbivorous mites, high control effect in the field, long lasting effect period, and less chemical agent consumption; The mixed use of hydrazine esters can increase the efficiency and reduce the dosage of active ingredients. Tannin can also reduce the amount of antifreeze and preservatives in the suspension, and reduce the cost of the preparation. The acaricidal composition containing bifenazate of the present invention is safe for plants, human beings and animals, has low pesticide residues in agricultural products, and meets the requirements of pesticide reduction and efficiency enhancement.

The invention relates to the technical field of pesticides and particularly relates to a farm-oriented bactericide. The farm-oriented bactericide contains Zhongshengmycin and pyrimethanil. The weight ratio of the Zhongshengmycin to the pyrimethanil is 1: (4-50). The farm-oriented bactericide is applied to preventing and treating plant fungal diseases and bacterial diseases. The synergistic effect is obvious and the field efficacy is high; a bacteriocidal spectrum is obviously enlarged and the prevention effects on cucumber gray mould, cucumber bacterial angular leaf spot, tomato grey mould, tomato leaf mould, early blight of tomato, tomato bacterial leaf spot, tomato mail head spot, tomato stem rot, pumpkin gray mould, pumpkin soft rot, cauliflower gray mould, garlic gray mould, chive gray mould, strawberry gray mould, grape gray mould, chili gray mould, cowpea gray mould, apple scab, apple altermaria leaf spot, pear scab, pear black spot and tobacco brown spot are very good; the prevention cost is reduced and the manpower of farmers is saved; and the technical threshold is low and the production process is simple.

The invention provides gossypol-containing acaricidal composition. Active ingredients of the gossypol-containing acaricidal composition comprise gossypol and spirodiclofen, a mass ratio of gossypol to spirodiclofen is 1:(10-50), and the composition is prepared from the active ingredients with total content being 5.5w.t%-52w.t% and the balance of auxiliary materials. A dosage form of the acaricidal composition is selected from one of wettable powder (WP), water dispersible granules (WDG), a microemulsion (ME), an emulsion in water (EW) or a suspension concentrate (SC). The gossypol-containing acaricidal composition has good effects on various phytophagous harmful acarids of crops and is high in field control efficacy and safe to plants, people and livestock, the usage quantity of a chemical agent is small, and the quantity of pesticide residues in agricultural products is small.

The invention relates to an agricultural fungicidal composition for plant pathogenic fungus-pythium. Each component and its weight percentage are respectively: 1-15% of hymexazol, 15-40% of copper acetate, 1-15% of auxiliary agent and 30-83% of filler. It is used for the prevention and control of Pythium root rot in vegetables such as garlic, ginger, and onion, and the effect is remarkable.
