Making avocado crops profitable in Ventura and Santa Barbara counties
What Has ANR Done?Working with growers, ANR campus- and county- based personnel began testing various methods for controlling root rot. This involved field studies to finally come up with a package of strategies to control the disease. Disease-control strategies include clonal rootstocks (disease-resistant), mounding, mulching, gypsum and some chemical treatments. Selection for more tolerant rootstocks continues, but now the rootstocks are also being selected for salt tolerance and resistance to other diseases. For the various waves of pests that have come through these orchards, we have devised biological control and management techniques, such as pruning and fertilizing to control these problems.
Avocado crop problems biologically controlledIn general, the avocado crop in Ventura and Santa Barbara counties is in good biological control, requiring few pesticides. The management practices developed by ANR have made avocados economically very attractive for coastal growers where the costs of labor, land and water are so high.
