[0034] Bioassay Example 1: Indoor Toxicity Test of Dikrysstrobin and Iprodione Compound on Tomato Early Blight, Apple Leaf Spot, Tobacco Red Spot and Peach Brown Rot

[0035] Test objects: Tomato early blight (Alternaria solani) and tobacco red spot disease (Alternaria alternata) were preserved in the strain room of this laboratory; apple leaf spot deciduous (Alternaria mali) was collected from Hebei and separated and purified by our laboratory; peach brown rot ( Monilinia fructicola) was provided by the Institute of Biology, Zhejiang University.

[0036]Test method: refer to the mycelial growth rate method of "Agricultural Industry Standard NY / T 1156.2-2006 of the People's Republic of China". Each agent is treated with 5 doses according to the content of active ingredients, and the above-mentioned pathogenic bacteria are cultivated with PDA medium. The bacteria block was moved to the center of the pre-prepared toxic PDA medium, and then cultured in a 25°C incubator, and each...

Abstract

The invention discloses an agricultural sterilization composition for controlling plant diseases due to alternaria and sclerotinia. The sterilization composition comprises kresoxim-methyl and iprodione, wherein a mass ratio of the kresoxim-methyl to the iprodione is 50:1-1:50. The invention further provides a fungicide. The fungicide comprises 1-80% by mass of the sterilization composition based on the active components, and the balance of an agrochemically-acceptable carrier and an auxiliary agent. The sterilization composition has characteristics of high performance, low toxicity, environmental protection, and facilitates treatment for germ resistance, and is especially suitable for controlling tomato early blight, alternaria mali, tobacco brown spot or peach brown rot.

Description

technical field [0001] The invention relates to an agricultural bactericidal composition, in particular to an agricultural bactericidal composition for preventing and controlling diseases caused by Alternaria and Sclerotinia. Background technique [0002] Alternaria can cause a variety of diseases in many crops, such as early blight, tobacco red spot and apple leaf spot. Early blight is a common disease of Solanaceae vegetables. In addition to tomato, it can also infect potato, eggplant, pepper and other crops. The main infecting body is conidia. Cause the middle and lower branches and leaves to wither early, resulting in a substantial reduction in production. Tobacco red spot disease is a serious disease that occurs widely in tobacco-growing regions of the world. Apple spot defoliation not only damages the leaves, causing early fall, but also damages new shoots and fruits, affecting tree vigor and yield. [0003] Brown rot caused by Monilinia spp. is one of the main dise...
