Other claims from this paper (16)

Intervention effect Verticillium wilt is controlled with resistant rootstocks.
Observation Botryosphaeria blight blights fruit clusters.
Observation Alternaria late blight defoliates trees.
Intervention effect Drip or buried drip irrigation reduced disease.
Intervention effect Pruning Botryosphaeria blight infections reduced overwintering inoculum and disease.
Intervention effect Dormant carbaryl and oil applications control phytocoris while being less toxic to beneficial insects.
Observation Trees compensate for early insect damage by maturing more remaining kernels.
Intervention effect Eliminating alternate hosts reduces Calocoris pests.
Recommendation Weeds should remain undisturbed from bloom until shell hardening when Lygus is present.
Observation Stink bugs can penetrate hardened shells and cause internal nut necrosis and epicarp lesion.
Intervention effect Degree day timing increases insecticide efficacy against navel orangeworm.
Intervention effect Degree day timing increases insecticide efficacy against obliquebanded leafroller.
Intervention effect Destroying unharvested overwintering fruit manages navel orangeworm more effectively.
Intervention effect Bacillus thuriengiensis sprays show promise for obliquebanded leafroller control.
Intervention effect Liquid lime sulfur shows promise for obliquebanded leafroller control.
Intervention effect Biological control shows promise for obliquebanded leafroller control.

Other claims from this paper (9)

Observation More than 70% of Nonpareil shells can split at nut maturity.
Intervention effect Mechanical shaking raised split-shell nuts by 40% relative to hand harvest.
Observation All shell splits occurred at the ventral suture.
Observation About 80% of splits occurred at the degenerating funiculus of the aborted secondary ovule.
Observation Remaining splits occurred near the viable ovule funiculus and rarely at the suture line.
Observation Secondary ovule abortion often begins at or shortly after bloom.
Observation The final shell-splitting site appears predetermined early in fruit development.
Observation At 50 days after flowering, inner endocarp walls were weak near developing funiculi.
Observation Eighty percent of leaffooted bug damage lay at the secondary funiculus attachment.
