The invention relates to a planting method for controlling pimento epidemic diseases by interplanting the field of pimento with garlic. The method includes the steps that ridging is conducted, the pimento is planted in a twin-row mode, the garlic is generally planted, three rows of garlic are planted every 6-10 rows of pimento in a pimento variety field in a mixed mode, and it is required that the pimento variety is about 10 cm higher than the garlic variety; the line spacing of the pimento is 40 cm, the planting distance of the pimento is 40 cm, the garlic is interplanted in field ditches, the line spacing of the garlic is 15 cm, and the planting distance of the garlic is 8 cm; the line spacing of the pimento and the garlic is 15 cm; pesticide liquid with the concentration being 250 mg/L is prepared through 50% dimethomorph wettable powder and warm water at the temperature of 55 DEG C before seedling cultivation, selected pimento seeds are steeped in the pesticide liquid, steeping and stirring are performed at the same time, and the seeds are fished out and dried after 20 minutes for seedling cultivation. According to the technology, by interplanting the field of pimento with garlic, the garlic can secrete allicin in the growing process, and the allicin accumulated in soil can deform pathogenic bacterium mycelia of the pimento epidemic diseases, deform spore germ tubes and reduce the spore germination quantity.

The invention discloses a microbicide composition and an application thereof. The microbicide composition comprises an active ingredient and a chelating agent, wherein the active ingredient comprises Zhongshengmycin and chitooligosaccharides, and the weight ratio of the Zhongshengmycin to the chitooligosaccharides to the chelating agent is 1: (0.1 to 15): (5 to 30). The chelating agent comprises at least one of edetic acid, sodium metaphosphate, sodium tripolyphosphate, ammonium citrate, potassium sodium tartrate and aminotriacetic acid. When wettable powder, water-dispersible granules and soluble liquid agents prepared from the microbicide composition disclosed by the invention and microbicides of other compositions and dosage forms are used in a tumble-blend manner, flocculation, precipitation and the like are not caused, and the pesticide effect of tumble-blend use is remarkably improved.

The invention relates to a processing method for preparing imidacloprid wettable powder from crude imidacloprid, which comprises the following steps: (1) firstly, adding filler into a mixer; (2) pouring crude imidacloprid of 50 to 60 DEG C into the mixer, starting up the mixer, and mixing for about 30 to 50 minutes; (3) adding wetting agent, dispersing agent and stuffing bulking agent, and mixingfor 30 to 50 minutes; (4) screening the uniformly mixed materials by a vibrating screen of 40 meshes; and (5) feeding the powder after being screened to a jet mill to be grinded, wherein, the weight percent of the components are as follows: 1-25% of imidacloprid, 5-50% of filler, 1-10% of wetting agent, 1-10% of dispersing agent and 5-50% of stuffing bulking agent. The invention can effectively solve the problem that the crude imidacloprid is difficult to be treated, and has the advantages of simple process and low treatment cost.

The invention discloses a pesticide composition containing folpet and fluopyram. The pesticide composition comprises at least two active components, i.e., folpet and fluopyram, wherein a weight ratio of folpet to fluopyram is 1: 5 to 20: 1, preferably, 1: 1 to 5: 1, and the pesticide composition has synergistic effect on crop control within the above proportional range. Any agriculturally acceptable dosage form may be prepared from the pesticide composition in the invention by using any conventional technical means available to those skilled in the art, and the dosage form includes, but is not limited to, missible oil, wettable powder, a suspension, a water-dispersible granule, an emulsion in water, a microemulsion and a granule.

The invention discloses an efficient environment-friendly pesticide compound composition. The dosage form of the composition is suspension emulsion, microcapsule suspension, a microcapsule suspending-suspending agent or wettable powder. The composition contains active ingredients of abamectin and ethiprole, and the balance of auxiliaries, wherein the weight ratio of abamectin to ethiprole is (1:5.5) to (1:9.5). The composition provided by the invention can prevent and treat multiple kinds of insect pests, and has the advantages of environment friendliness, slow release, long lasting period, reinforcement of adhesive force penetrating agents and no phytotoxicity.

The invention relates to a control method for bacterial blight of rice. The control method comprises the following steps: 1, ecological management: applying HYT (high yield technology) or Difulai microorganism fertilizer so as to improve soil physical and chemical properties, improve soil fertility and enhance the absorbing ability of rice roots; 2, agricultural control; 3, biological control; 4, biological prevention; 5, physical control; 6, chemical control: spraying 20 percent of bismerthiazol, 10 percent of chloramphenicol, 70 percent of phenazin or 25 percent of Yekuling wettable powder after a center disease plant is discovered. The bacterial blight of the rice can be effectively controlled; meanwhile, integrated control is performed by adopting measures of the agricultural control, the physical control and the like so as to reduce the average incidence of the bacterial blight of the rice, therefore the yield is increased; the grade of the rice is obviously increased; good economic benefit is obtained.
