How to control cotton bollworm when growing chrysanthemums? Please allow me to introduce the cotton bollworm on chrysanthemums: it damages the tender leaves and tender shoot tips of chrysanthemums, and after growing larger it bores into the tender buds and flowers to cause damage; in severe cases it can destroy large numbers of flower buds, so that they fail to bloom or form deformed flowers.

Cotton bollworm on chrysanthemums: it damages the tender leaves and tender shoot tips of chrysanthemums, and after growing larger it bores into the tender buds and flowers to cause damage; in severe cases it can destroy large numbers of flower buds, so that they fail to bloom or form deformed flowers.
Control methods: using Jiaduo frequency-vibration insect-killing lamps to kill adults has an obvious effect on reducing the number of eggs laid in the field; you can also use Lvge at 1500 times dilution, or 20% chrysanthemum-killing emulsifiable concentrate at 2000 times dilution, or 50% phoxim emulsifiable concentrate at 1200 times dilution, to kill newly hatched larvae.
