How do you control white rust in Achyranthes bidentata? Please explain the control methodsWhite rust in Achyranthes bidentata is mainly caused by a fungal infection of the plant. The symptoms are that all aboveground parts of the plant can be affected, and when leaves are damaged, pale yellow-green patches appear on the leaf surface, with blister-like raised spots developing on the corresponding underside, 1-2 mm in diameter. After the epidermis ruptures, a white, glossy, sticky, powdery substance is released, hence the name white rust. When many blister spots occur, the diseased leaves turn yellow, wither, and become brown; when they occur on parts such as leaf stalks and young buds, pale yellow spots appear and later become white blister spots, and the stems of affected plants are often swollen and distorted. White rust usually becomes more severe under conditions of low temperature and high humidity.
Control methods for white rust in Achyranthes bidentata:
1. Pay attention to crop rotation.
2. Deep plowing and removal of diseased plant residues. Early spring temperatures are low.
3. When there is a lot of rainfall, dig ditches to drain water and lower field humidity.
4. Starting in early March, spray 40% fosethyl aluminum at 200-300 times dilution, or use 50% thiophanate-methyl at 800-1000 times dilution, or use agents such as metalaxyl and Bordeaux mixture for control.
