The invention relates to a pesticide for plants. The pesticide is characterized by comprising the following components in parts by mass: 15.4-26.6 parts of garlic, 29.4-39.7 parts of onion, 2.4-2.6 parts of rheum officinale, 2.8-3.2 parts of radix sophorae flavescentis, 2-3 parts of sulphur, 2-3 parts of calamine, and 3.8-9.9 parts of 40% ethyl alcohol. The pesticide is easy to prepare and convenient to use; edible plants are used as the raw materials, so that the pesticide integrates insect prevention and control and plant nutrition supplementation and is pollution-free, residue-free and high in efficiency; the using amount of the plant pesticide is small, and the withdrawal time is not needed.

The invention relates to a pesticide application method capable of improving the wheat yield. According to the method, Baitai, Oubo, Gaoqiao, Shileshi, Alika, Handilong, monopotassium phosphatem, microelement mixed liquor high efficiency and low toxicity agentia are adopted; the method is carried out in four stages: wheat seed dressing stage, wheat standing and jointing stage, wheat heading stage and wheat filling stage; as the pesticide is applied according to different growth stages of the wheat, more than 90% diseases of the wheat can be efficiently controlled, the quality and the yield are improved, the medium trace elements required for the middle and later periods of fertility of the wheat can be met, the premature senility of the wheat at the later period can be prevented, the resistance to natural disasters is enhanced, and the pesticide application method is particularly suitable for planting of wheat.

The invention belongs to the technical field of forestry biologics, and discloses a growth agent for remedying damage of cinnamomun camphcra and a preparation method and application of the growth agent. The growth agent for remedying damage of the cinnamomun camphcra is characterized by consisting of indolebutyric acid, naphthylacetic acid, ferric phosphate, aluminum hydroxide, magnesium sulfate, ammonium nitrate and potassium stearate. The growth agent can be implemented in modes of spraying, coating and injection, growth and thickening of original tree barks and regeneration of new barks can be promoted, damaged bark remediation, maintenance and new and old bark growth can be achieved, damaged parts can be prevented from scar, burl and cavities, and moreover, insects can be killed. The growth agent is particularly applicable to landscapes, sidewalks, gardens and municipal administration.

The present invention discloses a melon disease prevention and cure method by utilising high-frequency electromagnetic wave treatment, belonging to the melon cultivation technical field. The specific content of the present invention is as follows: 5 to 7 days before seeding and raising seedlings, dressing the melon seeds with 250 gram diluted fungicide per 5 kilogram; after drying under the sun or by baking, treating the melon seeds with a high frequency electromagnetic wave of 25 to 30 MHz for 5 to 6 minutes. When the weight of the melon seeds treated by a single machine for multiple time is no greater than 5 kilograms, the current intensity is regulated up at a range of 0.5 to 12.5 amperes. By treating the melon seeds with the high-frequency electromagnetic wave, the method can effectively prevent the occurrence of damping-off, fusarium wilt, gummy stem blight, blight, powdery mildew, downy mildew, bacterial leaf spot and other diseases of melons during cultivation, and can avoid or reduce the spraying of pesticides during the entire growing period of melons, and reduces the pesticide residues of fruits and promotes a balanced ecosystem.

The invention relates to the field of pesticides preparations, and discloses a sterilization composition and a preparation thereof. The sterilization composition consists of tetraconazole and proquinazid with a weight ratio of 1 : (0.2-10), has substantial synergy effect, and is capable of effectively controlling powdery mildew of multiple crops, reducing the content of the pesticides and delaying generation of drug resistance. A bactericide of the invention is prepared from the sterilization composition, an auxiliary agent and a carrier, and is capable of effectively controlling powdery mildew of multiple crops, especially wheat powdery mildew and cucumber powdery mildew.

The invention discloses an emulsion in water containing metconazole and tebuconazole, and belongs to the technical field of blended pesticides. The emulsion in water is prepared by compounding the metconazole and the tebuconazole, and is a novel dosage form in which water is taken as a medium instead of an organic solvent in missible oil. When the emulsion in water is used for preventing and treating wheat scab, the using dosages of the metconazole and the tebuconazole as effective components can be lowered effectively. Meanwhile, compared with the metconazole and the tebuconazole in a single dosage, the emulsion in water has the advantages that the sterilizing effect is improved effectively, the cost is lowered, residues of pesticides on crops are reduced, and environmental pollution is lowered. The emulsion in water is safe to human beings and livestock, has high environmental compatibility, and is free from pesticide resistance.

A sterilizing composition containing benthiavalicarb-isopropyl and ningnanmycin is disclosed. The composition includes the benthiavalicarb-isopropyl and the ningnanmycin, as effective components, in amass ratio of 50:1 to 1:50, with the balance being allowable and acceptable auxiliary components for pesticides. The composition can be prepared into suspension concentrates, wettable powder, water dispersible granules, microemulsion, emulsion in water, granules and suspension concentrates for seed dressing through known methods. The composition has obvious synergistic effects, can be used for controlling a plurality of plant diseases on vegetables, fruits and other crops, and is particularly suitable for controlling downy mildew, late blight and powdery mildew.

The invention relates to a fungicidal composition containing active ester, which contains effective components of the active ester (A) and a pyrimidine fungicide (B), wherein the pyrimidine fungicide extracts from cyprodinil, fluorine mepanipyrim, mepanipyrim, fenarimol, nuarimol and the like, the mass ratio of A and B is between 100:1 and 1:100; and the mass percentage of the active components in the composition is 10-80%. The composition can be prepared to suspending agent, wettable powder and water dispersing granule. The fungicidal composition can be applied in the farmland and orchard and is used for preventing various plant diseases, particularly the powdery mildew and rust disease on the crops such as grain, vegetables, fruit tree and flowers.
