From Superweeds To Pierce’s Disease: California Agriculture Reports On Fighting Diseases And Pests

California agriculture is unique and diverse - and so are its pest and disease problems. Take herbicide resistance. While in the rest of the country herbicide resistance problems center on broadleaf weeds in corn, soy and wheat, in California the greatest problems are found in grasses and sedges in orchards, vineyards and rice fields. Herbicide resistance among California crops also varies widely. In vegetable fields, for instance, resistance is not a serious problem and is unlikely to become one.

An article in the current issue of California Agriculture, the peer-reviewed journal from the University of California Agriculture and Natural Resources, examines the spread of herbicide-resistant weeds in California and shows how UC researchers and Cooperative Extension specialists are helping growers to understand and manage the factors that drive it.
 
Five more articles in this special issue of California Agriculture highlight the work of UC Agriculture and Natural Resources on pests and diseases that threaten the state's people, agriculture and natural resources. The commitments to research and outreach profiled in the issue include the Endemic and Invasive Pests Strategic Initiative, the UC Statewide IPM Program and several successful collaborations with regulatory agencies and the agricultural community.

Cooperative efforts controlled spread of Pierce's disease and found genetic resistance
The 1999 arrival in California of a new Pierce's disease vector, the glassy-winged sharpshooter, posed a major new threat to California vineyards and orchards. A 15-year collaborative effort has successfully contained the sharpshooter and led to major improvements in our understanding of the biology of Pierce's disease, including promising advances in the development of disease-resistant grapevine lines.
 
Maintaining long-term management
 
Herbicide-resistant weeds challenge some signature cropping systems
 
Little or no crop rotation and limited herbicide options have contributed to the rise of herbicide-resistant weeds in orchards, vineyards and rice fields.
 
Over 35 years, integrated pest management has reduced pest risks and pesticide use
 
The UC Integrated Pest Management Program helps provide management solutions for invasive pests that destabilize IPM programs in agricultural and urban landscapes.

The cost of the glassy-winged sharpshooter to California grape, citrus and nursery producers
 
The spread of the invasive insect in the late 1990s led to increased costs and changes in agricultural practices for grape, citrus and nursery producers.

This is Making Harvest a Pain!

Video:

Harvesting the soybean fields this year feels more like driving our farm equipment through a maze than a field, because of the 13 inches of rain in June and replanted areas. Join me today as I take the reins of the combine and harvest the areas of the fields that are dry. Learn about why we drive around the wet soybeans and the current plan to harvest them. Also, see John Deere's Machine Sync in use between the combine and the grain cart tractor. It's pretty evident that harvesting the soybeans this year is going to take longer than years past because of how much our productivity is lessened due to all the extra turning around and driving in a random fashion.
