Observation: presence/absence
|
Rotate crops with vegetables such as celery, spinach, rapeseed, and garlic sprouts to reduce the source of overwintering insects.
|

Monitoring
Solution |
---|
Chemical treatments: in areas with a high risk of virosis, treat the beginning of the infestations.
|
Yellow board Monitoring practices: After the tomatoes are planted, yellow boards are used to monitor the dynamics. The yellow boards are set between the rows at the same height as the plants. 10 yellow boards are set per mu and replaced every 45 days.
|
Honda conducted a fixed-point survey to detect whitefly adults on the young leaves that unfolded at the top of the plant. The survey was conducted every 3-5 days, with 10 leaves surveyed at each point.
|
When there are 5-10 adult insects on each leaf of the upper leaves of tomatoes, pesticides should be used for prevention and control in time.
|
Control threshold is 10-20 plants showing symptoms per acre and/or at least 20 whiteflies on at least 10-20 plants per acre (Bemisia tabaci)
|
Use photoselective plastics with an insect repellent effect.
