Embodiment 1

[0014] In May 2014, 40 citrus trees were randomly selected in the citrus field of Zhongluotan Town, Baiyun District, Guangzhou City, Guangdong Province, and tested for Huanglongbing. The results showed that the incidence rate of Huanglongbing was 100%. The experimental design followed the principle of random selection, randomly selected 10 plants as the treatment group, and adopted the trunk infusion method to input the medicine (the main composition of each 100ml medicine was ampicillin 1 gram; cyclopentylpiperazine rifamycin, 0.2 gram; stabilizer : 1, 2-butanediol 1mL; antifreeze agent: ethylene glycol, 0.2 mL; new penetration aid: azone, 0.5 mL; dispersant: sodium lignosulfonate, 0.5 g; emulsifier: dodecyl Sodium benzenesulfonate, 0.5% g; co-solvent: DMSO, 0.5mL), and another 10 plants were randomly selected and input into clean water as a control, and the application began on May 1, once at the beginning of each month, and each application was 300mL. Infusion 4 times. Cit...

Embodiment 2

[0023] In April 2014, 20 citrus trees were randomly selected at the Dafeng Citrus Base in Guangzhou City, Guangdong Province, and tested for Huanglongbing. The results showed that the incidence rate of Huanglongbing was 100%. The experimental design followed the principle of random selection, randomly selected 10 plants as treatment groups, and adopted the trunk infusion method to input medicaments (the main composition of each 100ml medicament was 0.5 grams of ampicillin; cyclopentylpiperazine rifamycin, 0.5 grams; stabilizer : 1, 2-butanediol 0.5mL; new penetration aid: azone, 0.5 mL; dispersant: sodium lignosulfonate, 0.5 g; emulsifier: sodium dodecylbenzene sulfonate, 0.5 g; Solvent: DMSO, 1 mL), and another 10 plants were randomly selected and input into clear water as a control, and the application began on April 1st, once at the beginning of each month, each application was 300mL, and the infusion was 4 times in total. Leaf samples from the branches of the two groups of...

Abstract

The invention discloses an agent for yellow shoot prevention and control. The agent is applied by a trunk transfusion method. Each 100mL of the agent mainly comprises 0.5-1 gram of penbritin, 0.2-0.5 gram of rifapentine, 0.5-2mL of 1,2-butanediol serving as a stabilizer, 0.1-2mL of glycol serving as an anti-freezing agent, 0.1-2mL of azone serving as a novel permeation promoter, 0.1-2 grams of sodium lignin sulfonate serving as a dispersing agent, 0.1-2 grams of sodium dodecyl benzene sulfonate serving as an emulsifier, 0.1-2mL of DMSO (dimethyl sulfoxide) serving as a co-solvent and the rest deionized water supplemented to reach 100mL. Different bactericides are reasonably mixed by two sterilization mechanisms according to the objective requirement of yellow shoot prevention and control, the agent can achieve complementary advantages and has the advantages of high efficiency, low toxicity, safety, economization and multifunction, and yellow shoot can be more effectively prevented and controlled.

Description

technical field [0001] The invention relates to a composition of ampicillin fungicide and cyclopentylpiperazine rifamycin Rifapentine fungicide, which is applied by tree trunk infusion for the prevention and control of Huanglongbing. Background technique [0002] Citrus huanglongbing is an incurable and devastating disease, and it is also the most serious disease in citrus production in the world. After citrus plants are infected, they generally lose their commercial value after 2-3 years of being infected. Since its discovery, the disease has spread rapidly through seedling grafting and transportation and the vector of citrus psyllids, and has been widely distributed in more than 50 countries and regions including Southeast Asia, Africa, the Arabian Peninsula, India, Brazil, Florida and California in the United States. area. More than 100 million citrus trees in the world have been destroyed by Huanglongbing. Among the 20 provinces (cities, regions) where citrus is culti...
