Rootstock Options for California Almond Orchards

Nemaguard has been the workhorse rootstock of the California almond industry for many decades. It is well adapted to the well-drained, non-calcareous loam and sandy loam soils common throughout the San Joaquin Valley. Nemaguard is vigorous, immune to rootknot nematode, compatible with all almond varieties, doesn’t sucker much, has decent anchorage and is easy to grow at the nursery. However, th...

Remote sensing of spider mite damage in California peach orchards

Remote sensing techniques can decrease pest monitoring costs in orchards. To evaluate the feasibility of detecting spider mite damage in orchards, we measured visible and near infrared reflectance of 1153 leaves and 392 canopies in 11 peach orchards in California. Pairs of significant wavelengths, identified by Partial Least Squares regression, were combined into normalized difference indices. ...

Soil Acidity and Liming in Tropical Fruit Orchards

Based on these figures, it is no exaggeration to say that more than one-third of the Brazilian annual wealth is supported by a single natural resource: the soil. This justifies the impor‐ tance of studies on how to preserve and improve this valuable resource. According to [2], soils have natural limits to their ability to nourish plants and sustain crop productivity. The degradation of soil qua...

Effect of Preharvest Factors and Bruising in Stone Fruit Decay

In troduct ion The fruit skin (cuticle and epidermis) provides barrier protection against infection by pathogens. Most fungi are unable to penetrate healthy fruit skin and must enter through wounds. Fruit resistance to infection resulting from the biochemical action of tissues is not the result of a single compound or a single mechanism. Multiple systems with complex interactions may be involve...
