How to prevent and control insect pests and rodent pests in Fritillaria ussuriensis? Detailed methods

Wireworms (ginger worms) and white grubs are both underground pests that bite and feed on fritillary bulbs. Control: 800-fold dilution of trichlorfon can be used for drenching.

Cutworms (cutting worms) bite and feed on fritillary seedlings at night. Generally, 1 cutworm can damage 3 to 10 plants in one night. Control: scatter 2 kg of trichlorfon powder per 667 sq m, or spray with 800-fold dilution of trichlorfon.

Mole crickets bite and feed on fritillary bulbs and cut off the seedlings. Control: steam corn bait until hot, mix 50 g of trichlorfon per 5 kg to make poisoned bait for trapping and killing, or drench with 700-fold dilution of trichlorfon.

Zokors (blind mice) have a large appetite and bite and feed on fritillary bulbs; in autumn they also have the habit of storing fritillary bulbs. They are active every morning and evening and on cloudy and rainy days, are afraid of light and wind, and have keen hearing; if their tunnels have ventilation or light, they come to plug the holes. Control methods: 1. Take advantage of their hole-plugging habit and catch them manually; 2. Put rodent poison inside the white part of scallions, then place the scallions in the holes to trap and kill them, with very good results.

Moles (chuan di long) are insect-eating animals, but they tunnel through fritillary beds, causing fritillary seedlings to be exposed to wind and die. They can be caught manually when they come out to dig tunnels every morning and evening and on cloudy days, or trenches can be dug to block them.
