- Consider pest history and surrounding crops
- Consider crop rotations if a field had severe problems in 2017 with root knot nematode, verticillium wilt, fusarium wilt, or seedling diseases.
- Look at precision tillage and ripping for areas with a history of soil compaction, particularly if root knot nematodes are also a problem.
- Survey and manage weeds. Record your findings and treat if needed according to cotton pest management guidelines.
- Select a cotton variety based on local conditions and climate and field history of verticillium wilt, fusarium wilt and root knot nematode.
- Consider a seed treatment for pests based on field history and according to the cotton pest management guidelines for aphids, seedcorn maggot, seedling diseases, thrips and wireworms.
- Start planning for when to plant around March 5 by checking 5-day degree-day forecast and taking soil temperature.

California cotton experienced a nice rebound last season, increasing acreage to 298,000 acres, a 38 percent jump from 2016.
Of course, a drought busting rainy season that boosted water availability certainly buoyed growers and prompted them to plant more cotton. In 2017everyone is hoping the recent rains portend to wetter times ahead, especially after a fairly dry couple of months.
Breaking down the numbers, the USDA National Agriculture Statistical Services reported growers cultivated 208,000 acres of Pima in 2017, a 35.1 percent increase from the year before. Acala/Upland cotton acreage increased 45.2 percent to 90,000 acres.
Before the planting starts around April, growers will have a lot of winter work ahead.The University of California Integrated Pest Management Program offers these wintertime tasks for growers:
FIELD DAY: The San Joaquin Sustainable Farming Project is recruiting new almond, alfalfa and cotton growers in Merced, Madera and Fresno counties for the 2018 season. Growers can learn more about the program during a field day from 10 a.m. to noon on Thursday, February 15 at the Firebaugh Mendota United Methodist Church, 1660 O Street, inFirebaugh. Tom Casey of the Fresno County Agricultural Commissioner’s Office and Orvil McKinnis of the Westside San Joaquin RiverWatershed Coalition will provide updates about 2018 pesticide regulations and the watershed. For more information or to inquire about enrolling, please contact SJSFP/SCP Director Marcia Gibbs at (530) 370-5325 or firstname.lastname@example.org

Things are buzzing in almond orchards. And that’s before bees start flying, doing their pollinating thing in the trees.
Yes, before pollination starts there remains lots of winter work for growers and their field hands. They certainly have the work cut out for them.
|Almond growers produced a record yield in 2017.|
Why you might ask?
Well, growers will be pressed to surpass last season’s record year. The USDA is predicting a new high yield of 2.25 billion pounds from the 1 million acres of almonds across California. Almonds rank as the No. 3 farm commodity behind grapes and dairy.
To help growers start working toward another record year, field scout Jenna Mayfield offers her to-do list of winter chores:
- Survey the trees to make sure there are no more than two mummy nuts per tree by February 1. Jenna points out University of California researchers have found ignoring winter mummy nut sanitation leads to higher populations of overwintering navel orangeworm and greater kernel damage at harvest time.
- Inspect drip irrigation lines and sprinkler heads and make the necessary repairs. Growers don’t want to wait until they start irrigating next season and discover their drip lines are damaged.
- Fix the potholes on access roads. Growers can scrap the dirt and level to smooth the roadway.
- Remove loose or broken bark caused by shakers. These nooks could become winter havens for pests.
- Survey the orchard floor for weeds and identify those that were not controlled by a fall pre-emergent treatment. Record the findings. UC Integrated Pest Management says growers should consider applying a post-emergent treatment in January.
Here are other chores identified by the University of California Integrated Pest Management program:

- Take one more dormant spur sample this month for scale and mite eggs and compare results from earlier samples. Treat if necessary.
- Check trees for hiding places for peach twig borer. If treatment is needed, use a more environmentally friendly material or put off treatment until bloom.
- Monitor for rust in orchards with almond varieties that keep their leaves during the winter. Treatment would come in the spring.
- Watch for gophers and mound-building activity.

It’s finally feeling like winter with rain drops falling across the Valley early last week.
In the coming weeks, we’re going to offer winter to-do lists for alfalfa, almond and cotton growers.
Alfalfa tops 60,000 acres in the northern San Joaquin Valley. Statewide, growers cultivate about 800,000 acres a year. So there are plenty of winter chores before harvest starts later this spring.
Here is a to-do list from the University of California Integrated Pest Management Program:
- Continue surveying winter weeds through this month and keep a record of results.
- Determine weed management strategy based on 2017 weed types and abundance. You should consider applying pre- or post-emergence herbicide or a combination of both, appropriate for the weed pressure; overseeding with grasses and legumes in older, depleted stands; grazing or cultivating with a spring-toothed harrow, taking care to minimize damage to the alfalfa crowns.
- Note any special weed problems such as dodder and perennial weeds. Manage, if needed, according to the pest management guidelines.
- Start monitoring for aphids this month.
- Monitor for weevils by looking for chewed leaves, especially on stands putting on new growth. Take sweep-net samples when alfalfa height allows and manage if needed.
- Look for signs of vertebrate pests such as gophers, meadow voles or ground squirrels. Manage, if needed, according to the pest management guidelines.
- Scout for signs of stem nematode through March or April.
Growers can go to the UC IPM website to learn more about managing pests in alfalfa year-round.
