It’s that time of year again when hot weather fuels the creation of ozone, or smog. Some pesticides emit volatile organic compounds (VOCs) that contribute to ozone formation. Using pesticides that release VOCs may be restricted in certain California locations between May 1 and October 31.
If you plan to apply a pesticide, use the Department of Pesticide Regulation’s VOC calculators to determine emissions from fumigant and nonfumigant pesticides. You can get to the calculation site by going to the UC IPM Pest Management Guidelines: Citrus, click on a pest link and scroll down to the treatments. Click on the Air Quality button at the top of the treatment table.
Simple steps can minimize the release of VOCs into the air:
- Use pesticides only when necessary.
- Decrease the amount of pesticide applied if appropriate.
- Choose low-emission management methods.
- Avoid emulsifiable concentrate (EC) formulations and fumigants.
Ozone, or smog, is caused by mixing VOCs, nitrogen oxide, and sunshine. High levels of ozone can harm people and crops. Regions in California that do not meet federal or state air quality standards for ozone, called nonattainment areas, may restrict the use of pesticides that release VOCs.

Brigade WSB insecticide applied to skirt-pruned citrus trees is very important for preventing Fuller rose beetles from climbing the trunks and laying eggs on the fruit. FMC updated their 2ee trunk treatment recommendation to improve the explanation of how to properly apply the chemical to the trunk. Using the least amount of water possible provides more concentrated and longer lasting protection. However, concentration needs to be balanced with sprayability and avoiding contact with fruit. http://www.fmccrop.com/grower/Products/Labels-MSDS.aspx

KARE's new solar energy project has been completed. PG&E did their final safety checks for the new 42 kW solar system located at our Postharvest Facility. This brings KARE's solar output to about 65 kW. Special thanks to JKB Energy, Bob Ray, Patrick West, Andy Padilla, Santiago Aldana, Rudy Gonzales, Dan Mulligan, and Dale Pattigan for all of their hard work in helping to get this done. KARE will continue to get more green technologies on the Center. We continually strive to lower our carbon footprint and look at new and innovative ways to bring green technologies to our farming operations.
