Tulare County research revealed that an orchard's disease history influences how well annual copper fungicide treatments will work in controlling olive leaf spot. Elevated disease levels are not easily reduced in 1 year, and consistent annual treatme

Total water use was 18.8% greater for hedgerow plantings of walnut trees than for conventionally spaced trees during years 2 through 7 of this study. Cumulative yield-and revenue-water use efficiencies were much greater with the hedgerows through yea

Yields and fruit quality of French prune trees in Tulare and Yuba counties were not improved by controlling late-season prune rust with mancozeb or sulfur over a 3-year period. Accelerated postharvest leaf loss induced by disease did not appear to ca

In a 4-year study conducted on a deep, well-drained soil, irrigation cutoffs ranging from 12 to 45 days before harvest had only minor effects on prune production. Soluble solids tended to be higher and dry ratios lower with early cutoffs. There were

Brown discoloration of the core, carpels and flesh of ‘Ya Li’ and ‘Seuri’ Chinese pears during storage depends on harvest date, not storage temperature. In this trial, fruit harvested no later than 180 days after full bloom showed no signs of

Winter orchard sanitation is a major component of navel orangeworm (NOW) control in walnuts. “Mummy” nuts remaining in the trees shelter overwintering NOW. Once nuts are removed from the trees, shredding to destroy the protective shell ensures ma

In flight, codling moths prefer upper tree strata, whereas navel orangeworm oviposition is more evenly distributed throughout the tree. Pest monitoring and pheromone placement for mating disruption should recognize the vertical distribution of these

A once-in-a-century cold front, expressed as an advective freeze, damaged ‘Manzanillo’ extensively statewide. ‘Ascolano,’ ‘Sevillano’ and ‘Mission’ received minor damage. Damage included tip burn, defoliation, bark splitting and limb

Topically applied 'Sevillano' olive pollen increased the percentage of normal fruit set and reduced incidence of worthless shotberry 'Manzanillo' olives. Applications were effective up to 90 feet from the pollen source.
