Sustainability

The Federal Environmental Protection Agency's Pesticide Environmental Stewardship Program recognizes the California Walnut Board as a Silver Member, reserved for high achieving environmental stewards.

 

 

Integrated Pest Management is "the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment. IPM emphasizes the growth of a healthy crop with least possible disruption to agro-ecosystems and encourages natural pest control mechanisms." (Food and Agriculture Organization of the UN)

Air Quality

Walnut farmers in California address air quality issues using contemporary technologies that reduce pesticides, minimize dust and smoke, and reduce airborne particulate matter less than 10 microns (PM 10).  

Water Management

Profitable California walnut culture requires supplemental irrigation. The California Walnut Board has long provided significant financial support, on behalf of the California walnut industry, for research that provides tools for both efficient use of our limited water resources through scientific irrigation management and improves both surface and ground water quality due to reduced pesticide use within...

Soil Management

Maintaining orchard soil health is a fundamental priority of profitable walnut growers. Good tilth and optimal organic matter content receive constant attention.

The California Walnut Board’s research funding commitment to IPM (e.g. alternatives to soil fumigation, disease resistant rootstocks that don’t require pesticide protection, reduced pesticide sprays) has...

Energy Management

On-farm energy use is expensive and internal combustion engines further contribute to air pollution. California walnut growers and processors implement and emphasize technologies that reduce energy requirements and thus costs:
