Abstract

The invention relates to a resistance inducer for preventing and controlling tobacco bacterial wilt and an application thereof. The resistance inducer for preventing and controlling tobacco bacterialwilt mainly comprises citric acid and a synergist, wherein the synergist is composed of the following raw materials in parts by weight: 1-3 parts of chitosan, 2-4 parts of gibberellin, 10-30 parts ofcalcium nitrate and 1-3 parts of monopotassium phosphate. The resistance inducer for preventing and controlling tobacco bacterial wilt is capable of stimulating a series of metabolism regulation systems in plants to generate resistance substances, inducing resistance of tobacco plants to bacterial wilt or restraining the growth of germs, achieving the purpose of safely and efficiently preventing and controlling tobacco bacterial wilt and realizing 'primary green prevention and control, prevention and control through chemical decrement'.

Description

technical field [0001] The invention relates to the technical field of bacterial wilt prevention and control, in particular to an inducer for preventing and treating tobacco bacterial wilt and its application. Background technique [0002] Plant bacterial wilt (Bacterial Wilt) is caused by Ralstonia solanacearum and is considered to be "the second most important bacterial disease in the world". It has a wide host range and can infect more than 200 species of plants. crops are particularly serious. Tobacco bacterial wilt spreads all over the world's major tobacco-producing areas. It is a worldwide disease that can lead to destructive production failure and huge economic losses for tobacco farmers. It can be seen that effective control of tobacco bacterial wilt is an important prerequisite for safe production of tobacco leaves. [0003] Induced resistance response is to use the potential ability of crops to resist diseases. When crops are infected by pathogens or under adver...
