The extremely wet winter this year has likely helped growers to kill more overwintering navel orangeworms (NOW) than in warmer and dryer winter years. However, a wet, cold winter will not kill all NOW, and being complacent might result in a bad NOW year. Continue reading
Reducing weed control in orchards during difficult economic times is possible but comes with some tradeoffs. It’s useful to step back and remember why we’re controlling weeds in the orchard in the first place. Continue reading
Determining the priority for pesticide sprays for insect pests is challenging. Integrated pest management uses cost/benefit analysis to guide growers and farm managers in making pest control decisions. Continue reading

Most challenging for the topic of watersheds has been a shift towards increased use of pyrethroids. In general, the amounts found are low, nevertheless, cases of exceedances do occur, and these cases need to be eliminated. Continue reading
New studies show that almond hulls and shells can be used as low-cost organic matter amendments and can release potassium into the soil. This can help increase soil exchangeable potassium with benefits to July leaf potassium values, and in the long term, could build soil organic matter content while reducing dust and erosion.
