With the combination of sterol inhibitor (triadimefon) and strobilurin (trifloxystrobin), Strike Plus provides systemic and translaminar activity on many diseases including powdery mildew, rusts, scab, black spot, leaf spots, downy mildew and others. The combination lessens the high resistance potential that users face when using a strobilurin fungicide by itself.

OHP will phase out Strike 50 WDG but will maintain federal and state registrations for a period of time so growers can use up existing stock.
