Prevention and control of rust on primary parasitic plants should be sprayed 1 or 2 times in mid-March to kill overwintering spores. In the growing season, when the new leaves are unfolded, they can use 25% triadimefon 1500-2000 times, 50% mancozeb 500 times, or 25% methosoldine wettable powder 800 times every 7-10 minutes. Once a day, continuous control 2 to 3 times. Can also be used 50% Veratryin WP 1500 times spray.
