How to control the Euonymus leafroller moth at the right time?
The Euonymus leafroller moth, also known as the Euonymus moth, is one of the earlier leaf-eating pests to harm garden plants. After several years of observation, the author found that in the Xi'an area its larvae appear in late March, mainly harming plants such as Euonymus japonicus (evergreen euonymus), Euonymus bungeanus (winterberry euonymus), and Euonymus fortunei (climbing euonymus). In severe cases they eat all the leaves, affecting the ornamental effect. When low-instar larvae are found causing damage, spray evenly with 50% phoxim emulsifiable concentrate or 40% omethoate emulsifiable concentrate at 1000 times dilution, or with 2.5 deltamethrin emulsifiable concentrate at 2000 times dilution; the control effect is very good.
