General Situation: Daily high temperatures will be swinging between the low 70s and low 90s F over the next 10 days.  These are ideal conditions for thrips development. 

Thrips development: Generation 2 adults are peaking right now.  Generation 3 will be developing on plants this month, and reaching peak adult numbers around June 3rd.  Generation 4 will be developing on plants during June, reaching peak adults around June 27th.  For most crops these two generations will present the highest risk of TSWV spreading and causing yield loss.  Focusing thrips treatments into the next 8-9 week window will help keep TSWV damage to a minimum.
