example 1

[0017] Bioassay Example 1: Indoor virulence assay of fludioxonil and Ningnanmycin complex against Rhizoctonia sheath blight

[0018] Test object: Rhizoctonia cerealis Van der Hoeven, collected in the field, isolated and rejuvenated by laboratory three times.

[0019] Test method: The test refers to "Indoor Bioassay Test Guidelines for Pesticide NY / T1156.2-2006 and 1156.6-2006", and the growth rate method (plate method) is used in this test. On the basis of the preparatory test, on the sterile operating table, quantitatively add the pre-melted sterilized medium into the sterile conical flask according to the test treatment, and add 5 mL of the medicinal solution from low concentration to high concentration to the container respectively. Put 45mL of hot medium (PDA medium, 45-50°C) in a conical flask, shake well, quickly pour it into a 90mm diameter glass petri dish, and pour 10mL of medicated medium into each petri dish. Let stand horizontally and make flat after cooling. Fiv...

Embodiment 1

[0045] Formulation Example 1: 41% Fludioxonil·Ningnamycin WP

[0046] Formula composition: active ingredient fludioxonil 40%, active ingredient ningnamycin 1%, sodium lauryl sulfate (wetting agent) 6%, naphthalene sulfonate (diffusing agent) 5%, sodium lignosulfonate (dispersant) 7%, kaolin (filler) to make up to 100%.

[0047] Suspension Example

[0048] The pesticide active ingredients, dispersants, wetting agents, thickeners, defoaming agents, preservatives, antifreeze agents and water are mixed uniformly according to the proportion of the formula, and the suspension is obtained after grinding and / or high-speed shearing. agent product.

Abstract

The invention discloses an agricultural sterilization composition. Effective components of the agricultural sterilization composition comprise fludioxonil and ningnanmycin; a mass ratio of the fludioxonil to the ningnanmycin is (40:1) to (1:40), and other components are pesticidally available and acceptable auxiliary components. The composition can be prepared into suspension, aqueous capsule suspension, suspended seed coating, and wettable powder or water dispersible granules by an existing method. After the fludioxonil and the ningnanmycin are compounded according to a certain ratio, the agricultural sterilization composition has an obvious synergism effect and is mainly used for preventing and treating wheat sharp eyespot and cucumber gray mold.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to an agricultural bactericidal composition, in particular to an agricultural bactericidal composition containing fludioxonil and its application for preventing and treating crop diseases. Background technique [0002] Fludioxonil (Fludioxonil), molecular formula: C 26 H 23 F 2 NO 4 , is a new type of pyrrole non-systemic broad-spectrum fungicide developed and produced by Syngenta. Its mechanism of action is to inhibit the growth of fungal mycelium by inhibiting the transferase related to the phosphorylation of bacterial glucose, resulting in Germs die. It has a good protective and therapeutic effect on diseases caused by pathogenic bacteria such as Alternaria, Ascoidis, Aspergillus, Fusarium, Helminthosporium, Rhizoctonia and Penicillium. Fusarium rot, wheat black rot, blight, etc. [0003] In recent years, due to single drug use and other unscientific drug method...
