Embodiment 1

[0021] Toxicity Measurement Example 1 Indoor Toxicity Measurement to Strawberry Root Rot

[0022] Test object: Strawberry root rot

[0023] Test method: refer to the standard method of bioassay NY / T 1156.2-2006, using the medium method containing medicine: take 3mL of the medicine solution with a series concentration of each single agent and mixed agent, add it to 27mL PDA medium cooled to 45°C, and prepare Prepare the drug-containing medium plate at the desired final concentration. Then, a 6mm-diameter hyphae piece was prepared from the edge of the pathogen colony cultured for 7 days, and moved to each series of drug-containing medium, with the hyphae facing down, and each treatment was repeated 4 times. After the treatment, culture in a constant temperature biochemical incubator at 25°C, measure the colony diameter after 4 days, and calculate the growth inhibition rate. Through the linear regression analysis between the probability value of the inhibition rate and the loga...

Abstract

The invention discloses a granule bactericidal composition containing amino-oligosaccharin and hymexazol. The granule bactericidal composition comprises an effective component A amino-oligosaccharin and an effective component B hymexazol, with the mass ratio being 2:1 to 1:10, and preferably the mass ratio being 1:2 to 1:5. The bactericidal composition has an obvious synergetic effect, can reduce the consumption of pesticides, the residual amount of pesticides on crops and the environmental pollution, is safe for people and livestock, good in environmental compatibility, and ensures that diseases are not easy to develop insecticide resistance. The bactericidal composition has the purpose of preventing and treating soil-borne diseases, and has obvious control effects on foot rot and blight.

Description

technical field [0001] The invention relates to a granule fungicidal composition containing amino oligosaccharin and hymexazol, belonging to the technical field of pesticides. Background technique [0002] Soil-borne diseases refer to diseases caused by pathogens such as fungi, bacteria, nematodes and viruses that live in the soil with diseased residues and attack crops from roots or stems when conditions are suitable. Infection pathogens include fungi, bacteria, actinomycetes, and nematodes. Among them, fungi are mainly divided into non-obligate parasitism and obligate parasitism. Non-obligate parasitism is ectophytic root-infecting fungi, such as Pythium spp. causing seedling rot and damping-off, and Rhizoctonia causing seedling blight. Obligate parasitism is a plant microtubular bundle pathogenic fungus, typically wilting and dying caused by Fusarium oxysporum and Verticillium alboatum. The severity of root disease is controlled by the composition and concentration of ...
