General Situation Despite relatively high thrips counts in some areas, TSWV incidence remains low generally. Any younger crops will remain susceptible to economic damage until fruit set. Temperatures over the next 10 days are set to hover in triple digits for 5 days before cooling off to the mid 90sF. This heat wave might slightly delay thrips development and thin the population out a little.
Thrips We are in the middle of generation 4 maturing on plants. Nymphs feeding on infected plants at the moment will turn into infected adults and could spread any TSWV more widely. Generation 5 will mature during the first half of July. After that most crops will be beyond risk. Consider continuing treatments until all crops have set fruit and are passed the early growth period where damage can be heavy. If you want to see thrips degree day projections for your own crops, our new user interface lets you drop a pin on a map and generate a projection for that location specifically.
