Problems solved by technology

If the mycelium is not processed into preparations, the necessary growth conditions cannot be guaranteed, causing it to lose its activity and reduce the control effect. At the same time, the maximum control effect can be exerted only by relying on the carrier of the preparation. Really put into production and practical application
At present, there is no relevant report about Phoma herbaceous being processed into water-dispersible granules

Abstract

The invention relates to phoma herbarum water dispersible granules and a preparing and using method thereof. The phoma herbarum water dispersible granules are prepared from 15 parts of phoma herbarum,2-8 parts of a wetting agent, 2-6 parts of a dispersing agent, 2-8 parts of a disintegrating agent, 4-6 parts of an adhesive, 5-7 parts of a stabilizer and 50-70 parts of a carrier. The preparing method of the phoma herbarum water dispersible granules comprises the steps of preparation of phoma herbarum hyphae, mixing, kneading, pelleting and drying. Mist spraying treatment is conducted in the 3-4-leaf stage of commelina communis L and the 3-4-leaf stage of amaranthus retroflexus, the pesticide application amount is 228-236 g / mu, mist spraying is conducted once every 7 days, and mist sprayingis totally conducted 3 times. By means of the preparing and using method, the biocontrol bacterium phoma herbarum is processed into the water dispersible granules, the biocontrol activity of the phoma herbarum is guaranteed, the granules are safe to operators and environments, the concentration of effective components is high, the storage stability is high, and the shelf life is long.

Description

technical field [0001] The invention relates to biological pesticides, in particular to a Phoma phlox water-dispersible granule and a preparation and use method thereof. Background technique [0002] Commelina ( Commelina communis L ) is a vicious weed in the field, with rapid growth, strong damage potential, and strong adaptability in the field. Artificial weeding is not effective, and chemical weeding has problems such as pesticide residues, environmental pollution, and drug resistance. The use of biological control of weeds can provide a new way for weed control. [0003] Phoma ( Phoma herbarum ) is a pathogenic fungus isolated from the diseased Commelina miltiorrhiza. Phomophora phlox can infect Commelina praecox and cause its death. When the fungal herbicide conditions are suitable, it can be applied in large doses in the field to artificially create target weeds. The disease pandemic, so as to quickly and effectively control weeds. Fungal herbicides have the chara...
