1909 results about "Fungicide" patented technology

Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants.

Composite microbial fertilizer for controlling crop diseases and insect pests, and preparation method thereof

The invention relates to a composite microbial fertilizer for controlling crop diseases and insect pests, which contains composite microbial fungicide and is prepared by the following raw materials based on parts by weight: 10-35 parts of composite microbial fertilizer fungicide, 3-15 parts of composite microbial pesticide fungicide, 1-5 parts of insecticidal synergist, 1-5 parts of plant growth regulator, 20-60 parts of grass carbon, 5-15 parts of expanded chicken manure, 5-50 parts of inorganic fertilizer and 1-3 parts of binding agent, wherein the composite microbial fertilizer fungicide is prepared by bacillus megaterium and jelly-like bacillus; and the composite microbial pesticide fungicide is prepared by mixing bacillus thuringiensis and bacillus subtilis, adding sodium percarbonate type solid state oxygen-increasing agent for mixing and fermenting and finally absorbing by the grass carbon. The composite microbial fertilizer adopts strains with good suitability, and the strains are compounded according to a certain proportion to obtain the composite fungicide which has durable activity and stable performance; and the four beneficial strains are compatible with each other and performs the own functions, so that the multiple aims of resisting germs as well as diseases and insect pests, and increasing the crop yield can be achieved.

The invention relates to an application method of arbuscular mycorrhizal fungus in large-scale tobacco cultivation. A primary arbuscular mycorrhizal fungi fungicide is inoculated and propagated separately, and propagule spore density of an arbuscular mycorrhiza of each fungi after the propagation is 30 pieces per gram of dry soil. A float breeding method is adopted to conduct arbuscular mycorrhizal fungi fungicide combinedinoculation to tobacco, mycorrhization tobacco seedlings are obtained, and the mycorrhization tobacco seedlings are directly applied to field production. When being transplanted, the mycorrhization tobacco seedlings are conducted with a two-step inoculation, and the mixed fungicide is mixed by propagated acaulospora mellea, glomus mosseae and glomus intraradices at a proportion of 0.5-1: 1:1. A colony formed by the propagation of the arbuscular mycorrhizal fungus is close to a natural state, and fungus cooperate and play a better role of growth promoting and quality improving. According to the application method of the arbuscular mycorrhizal fungus in the large-scale tobacco cultivation, by means of the two times of inoculations of the arbuscular mycorrhizal fungus, the proportion of arbuscular mycorrhizal fungus and the tobacco in a symbiotic system built during a seedling stage of the tobacco is guaranteed, and the beneficial effects of the symbiotic system to the development of the tobacco seedlings are ensured. The application method of the arbuscular mycorrhizal fungus in the large-scale tobacco cultivation is simple and practical in method and environment friendly.

Compound microbial fertilizer and preparation method thereof

The invention discloses a compound microbial fertilizer, comprising the following raw materials in parts by weight: 40-50 parts of crop straws, 50-60 parts of swine wastes, 20-24 parts of bean pulp, 12-16 parts of egg shells, 10-15 parts of vinasse, 20-25 parts of attapulgite, 18-22 parts of medical stones, 6-8 parts of schaumgyps, 10-12 parts of humus, 4-5 parts of lupulus, 5-6 parts of sophora alopecuroide, 3-4 parts of radix isatidis, 4-6 parts of sweet wormwood, 1-2 parts of EM fungicide and a proper amount of water. According to the compound microbial fertilizer disclosed by the invention, agricultural and sideline products such as the crop straws, the swine wastes, the bean pulp and the like are taken as main raw materials, so that the compound microbial fertilizer not only is available in materials, low in price and cost, and abundant in nutrient, but also can improve the soil structure; the added vinasse contains a plurality of organic compounds, vitamins B and cellulose, also contains abundant crude proteins and crude fat, can be used as an energy source fertilizer, and assisted with multifunctional natural raw materials with abundant nutrients, such as the attapulgite, the medical stones and the like, so that the compound microbial fertilizer has the advantages that the water-retaining property, the adsorbability and the like of the soil are increased. By adopting the fertilizer disclosed by the invention, resources are fully utilized, productive investment is reduced, the pollution caused by a chemical fertilizer is reduced, and the compound microbial fertilizer has certain environmental and economic benefits.
