Powdery mildew is identified by the white, powdery growth on leaves and shoots that consist of the fungal[Read More…]
Shoots are at various stages of development across the state with some shoots at or near bloom.

Tank mixtures (or tank-mixing) describes the process where multiple crop protection chemicals are combined in a single tank for simultaneous application. Tank-mixing pesticides allows the grower to make a single application but manage multiple pests AND pesticide resistance issues. All specialty crops, especially fruit crops, have more pests and pathogens than field crops, along with[Read More…]
