Peach

Oriental Fruit Moth (OFM): The third flight and all required treatment timings are now over throughout the state. Additional treatments will only be required on very late varieties, and only if trap counts exceed 6 moths per trap. We are seeing some high trap captures in some orchards.

Tufted Apple Budmoth (TABM): We are in the middle of the second flight, but pest pressure is very low. On most farms treatments are not needed. If you did have feeding injury from the first generation or have high trap counts, then you may wish to observe the following TABM timings.

Brown Rot Management in a Wet Growing Season: Part III

Brown rot of peach and nectarine fruit results from the interaction of many different factors. In Part I of this series, we discussed the various sources of inoculum and their importance for disease development (see July 21 posting). In Part II, we examined the many facets of spray application technology and [Read more…]

Brown Rot Management in a Wet Growing Season: Part II

In part I of this article series, we discussed the sources of inoculum for fruit infection by the brown rot pathogen, Monilinia fructicola (see July 21, 2015 article).

Air-blast application of fungicide to peach.

Although measures to reduce the inoculum from these sources were presented, these cultural controls alone only provide partial control. They are to be used in conjunction with other measures in an integrated program. And every facet of this program needs to be fine-tuned for optimum performance, especially in a wet growing season.
