The invention discloses a bactericidal composition containing azoxystrobin, a pesticide with the composition, and application of the composition. The bactericidal composition is composed of azoxystrobin and cuppric nonyl phenolsulfonate at the mass ratio of 1:20 to 20:1 and at the preferable ratio of 1:10 to 10:1. The composition is an effective ingredient and can be combined with acceptable auxiliary ingredients in the pesticide to form the corresponding bactericidal pesticide. Experiments prove that after being compounded, the azoxystrobin and the cuppric nonyl phenolsulfonate can generate a remarkable synergistic effect in the prevention and cure of fruit and vegetable crop diseases such as cucumber downy mildew, bacterial angular leaf spot or cucumber blight, the resistance to drugs can be delayed, the amount of single dosage is reduced, the cost is lowered, and the applicable range can be expanded.

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 provides a water culture method for Chinese flowering cabbage and belongs to the field of agricultural production. Chinese flowering cabbages are planted in a greenhouse provided with afly net. According to biological characteristics of Chinese flowering cabbages and insect pest occurrence characters, seedling culture, design and application of water culture devices, efficient culture technique are integrated and optimized full all sides, and thus a simplified water culture device and a water culture method for Chinese flowering cabbages are obtained. By the method, Chinese flowering cabbages reach green standards, have high yield and good quality.

The invention provides a sterilization composition and application thereof, and belongs to the field of agricultural bactericide. Effective components comprise fluopicolide and eugenol. The sterilization composition is low in resistance risk, good in medicinal effect, long in lasting period and low in environmental pollution. According to the sterilization composition provided by the invention, the fluopicolide and the eugenol are used as the effective components; the weight ratio of the fluopicolide to the eugenol ranges from (30: 1) to (1: 30). The sterilization composition can be used for preventing and treating diseases of crops and is particularly obvious in effect on cucumber downy mildew.
