Problems solved by technology

[0003] Although various chemical fungicides for the prevention and treatment of anthracnose such as turpentine copper, thionitrile bacteria, prochloraz, etc. have been researched and developed at home and abroad, these fungicides have the following disadvantages in summary: short drug effect, and the bacteria are prone to drug resistance; In the case of continuous rain, the medicine is easily diluted and washed by the rain and loses its efficacy; it has residues and is easy to pollute food and the environment
However, it is different from conventional chemical fungicides and does not have a bactericidal effect by itself

Embodiment 2

[0037] Implement pesticides: 50% high lipid film fungicide containing prochloraz.

[0038] Implementation layout: Trials were grouped diagonally, with two replicates for one treatment and two controls.

[0039] Implementation of treatment: On the basis of conventional treatment, spray 50% high-fat film fungicide containing prochloraz once every 30 days after flowering, and shorten it to every 15 days after entering the rainy season and before the ears are harvested once. The first spraying was carried out at the early fruit stage on April 28, the second spraying on May 13, the third spraying on June 2, the fourth spraying on June 24, and the harvest on July 14 .

Abstract

A plant bactericide fro preventing and treating the anthracolemus of fruit tree contains oily prochloraz emulsion (14-24 Wt%), high-fat film emulsion (74-84), cinnamic ketone, acrylic acid emulsion (1.2-1.5) and organic silicon defoaming agent (0.5-0.8).

Description

Technical field: [0001] The invention relates to a fungicide for preventing and treating fruit tree anthracnose [Colletotrichum gloeosporioides (Penz.) Sacc.], belonging to the technical field of chemical pesticides. Background technique: [0002] Anthracnose of fruit trees such as grapes, bananas, and mangoes is a worldwide disease, and the annual fruit yield loss caused by the disease is about 10% to 30% in the world. This disease can harm all green parts such as leaves, new shoots and fruits of fruit trees. Especially in the fruit ripening period, if there is continuous high temperature and rainy season, it is difficult to carry out effective chemical control, resulting in fruit rot, and the incidence rate is basically the loss rate. [0003] Although various chemical fungicides for the prevention and treatment of anthracnose such as turpentine copper, thionitrile bacteria, prochloraz, etc. have been researched and developed at home and abroad, these fungicides have the ...
