[0026] Indoor bioassay example 1: Toxicity determination of fludioxonamide and fludioxonil compound against zucchini root rot

[0027] Test object: zucchini root rot [Fusarium solani (Mart.) App.et Wollenw. formacucurbitae].

[0028] Test method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006", using the drug-containing medium method.

[0029] Data statistics and effect evaluation: Calculate the mycelium growth inhibition rate (%) according to the test data, find the toxicity regression equation, and calculate the EC 50 . The co-toxicity coefficient method (CTC) was used to evaluate the synergistic effect of drug mixture. CTC≤80 was antagonism, 80<CTC<120 was additive, and CTC≥120 was synergistic.

Abstract

The invention relates to a bactericidal composition containing fludioxonil and flutolanil and application of the bactericidal composition. The composition contains fludioxonil and flutolanil, wherein a weight ratio of fludioxonil to flutolanil is (1-40):(1-40). The composition can be applied to prevention and treatment of crop root rot. The composition is wide in application range, good in effect, low in cost, low in residue and safe to human, livestock, environment and the like.

Description

(1) Technical field [0001] The present invention relates to a bactericidal composition and its use, in particular to a bactericidal composition containing fludioxonil and fluoroamide, which is mainly used for the prevention and treatment of crop root rot. (2) Background technology [0002] Fludioxonil (Fludioxonil) is a new type of non-systemic phenylpyrrole fungicide, which inhibits the transfer related to the phosphorylation of bacterial glucose and inhibits the growth of fungal mycelium, leading to the death of pathogenic bacteria. Seed treatment has excellent control effect on various soil-borne and seed-borne diseases. [0003] Flutolanil is an anilide fungicide, and its mechanism of action is as a succinate dehydrogenase inhibitor in the electron transport chain of respiration, inhibiting the synthesis of aspartate and glutamate. Fluoramide has protective and curative activity, and can be used for the prevention and control of diseases of rice, cereals, potatoes, suga...
