chosen from the inside and outside of the canopy. Examine
both sides of the leaves looking for pest mites and predators.
Note the number of leaves on each tree with pest mites and
their eggs, and the number of leaves with predators. There
is no need to count the mites. Once completed, compare the
numbers with the guidelines provided in the “Don’t Treat”
and “Treat” columns on the sampling form provided in the
UC Almond Pest Management Guidelines
.
Many miticide options exist for cases where a treatment is
required. Each miticide has its strengths and weaknesses,
and for that reason options should be discussed with a pest
control advisor. For almond growers in the San Joaquin
Valley that plan on using miticides containing abamectin,
keep in mind that new regulations require that only low-
VOC formulations be used between May 1 and 31, October
2015 and 2016. More details on this new regulation and
all miticide options can be found in the
UC Almond Pest
Management Guidelines
.
Final Thought
Often, wet years come in pairs. Early rains can impact
harvest. Applications of RDI through June can reduce the
duration of hull split, which will shorten the harvest period.
This strategy is one of the few ways to prepare for the risk of
early rains that we may experience in the fall.
