Preparing soil for winter can protect soil health
Farmers placed clumps of soil into metal mesh baskets, submerged the baskets into jars of water, then watched to see if their soil held together. The slake test, conducted at the Soil Health Field Day in Woodland, measured soil health. Healthier soil,...

Powdery mildew of melon is a common problem in all California melon production areas and multiple fungicide applications are used to control it. Resistant melon varieties are available, but plant resistance-breaking strains of this pathogen can render them susceptible. In addition, some fungicides are no longer effective due to the development of fungicide-resistant strains of the pathogen.
The most sustainable control strategy integrates the use of varieties with mildew resistance and prudent use of fungicides. In this way, an entire melon producing area is not completely reliant on either approach to control the disease. Also, rotation of fungicides with different modes of action is an important strategy in reducing selective pressure that causes resistance. A search for such fungicides may lead to registration of new materials. This would aid in mildew control and resistance management.
In addition, there is a need to assess powdery mildew susceptibility of modern melon varieties in the low desert production area of California.
