[0027] Biological Assay Example 1: Indoor Toxicity Test of Composition to Botrytis Botrytis

[0028] The test object is Botrytis cinerea

[0029] The mycelial growth rate method was used in the test. Take 5ml of the prepared experimental drug solution and add it to an Erlenmeyer flask equipped with 45ml of hot medium (PDA medium, 45-50°C). After shaking well, quickly pour it into a 90mm diameter glass petri dish. Add 12ml of drug-carrying medium, 4 replicates for each treatment, place it horizontally, and form a plate after cooling. Use a 5mm diameter punch to cut the fungus cake from the edge of the test bacteria that has been cultured for 5 days, and use a pick needle to connect the side with mycelium to the poisonous medium. All operations are performed aseptically on the ultra-clean workbench. After the treatment, the plates were cultured in a constant temperature sterile incubator at 25°C. After 5 days, the colony diameters of each treatment were measured by the cross m...

Abstract

The invention discloses a pyribencarb bactericidal composition. The bactericidal composition comprises an active component A and an active component B, wherein the active component A is pyribencarb, the active component B is bixafen or benzovindiflupyr, and a mass ratio of A to B is 1: 50 to 50: 1. The composition of the invention is obvious in synergism, high in prevention efficiency and applicable to prevention and treatment of a plurality of diseases attacking fruit and vegetable, especially to prevention and treatment of gray mold attacking cucumbers, grapes, strawberries and tomatoes.

Description

technical field [0001] The invention relates to a fungicidal composition, in particular to a fungicidal composition mainly composed of pyribencarb and its application in preventing and treating crop diseases, belonging to the technical field of pesticides. Background technique [0002] Botrytis cinerea, also known as gray rot, is one of the main diseases of grapes. The pathogen is Botrytis cinerea, which belongs to the fungus of the genus Botrytis. The pathogen mainly harms inflorescences, young fruits and fruits that are about to ripen. Botrytis cinerea occurs heavily in low-lying vineyards with overgrown new shoots, poor ventilation and light transmission, extensive management, overgrown weeds, insufficient fertilization, and severe insect damage. Because Botrytis cinerea can spread and harm occurs, it often causes the death of large areas of plants, resulting in reduced yield and poor quality, which seriously restricts the development of grape production. At present, th...
