The 13th Concho Valley Cotton Conference conducted by the Texas A&M AgriLife Extension Service is set for 8 a.m. to 3:15 p.m. March 7 at McNease Convention Center, 500 Rio Concho Drive in San Angelo.
“There’s a lot of new information relating to West Texas cotton production, and this biennial conference is a good place to catch up on what’s going on,” said Josh Blanek, AgriLife Extension agent in Tom Green County. Continue reading

Both Clemson University and North Carolina State University are issuing warning bells for nematodes in the Carolinas.
The nematode issue was front in center at both Clemson’s corn and soybean production meeting in Dillon, S.C., Feb. 8 and at N.C. State’s Road Show production meeting the following day in Plymouth, N.C. A concern in both states is the Southern root knot nematode and the soybean cyst nematode. Continue reading

Louisiana witnessed a shift from root-knot to reniform nematodes in the late 1980s and 1990s. “We conducted nematode survey work in cotton in the mid-1990s, and found that 50 percent of the fields had reniform and only 25 percent had root-knot,” says Louisiana State University AgCenter plant pathologist Charles Overstreet.
“However, we’re now moving slightly back in the other direction because we’re rotating more with corn; we’re now finding a mixture of both reniform and root-knot in cotton fields. Corn is a host for root-knot, but not reniform, so yearly rotation helps manage reniform nematodes. Many Louisiana growers now plant one year with cotton and one with corn.” Continue reading

Bob Kemerait, University of Georgia Plant Pathologist
“What exactly is it you do?” I am asked time and again. “I am a plant pathologist for the University of Georgia,” I say, which is met with a blank stare until I say, “That is like being a veterinarian for plants.”
In truth, “a veterinarian for plants” may not be the best description. Plant pathologists are less able to heal a single affected plant than they are to protect an entire crop. I have begun to think of my vocation as more of a “zookeeper,” which is a better moniker for corralling and containing a host of wild beasts like fungi, bacteria, nematodes and viruses. When these beasts escape, for they are truly cunning, it is my job to work with farmers, Extension agents, consultants, researchers and agricultural industry to put them back in their cages as quickly as possible.

A $450,000 grant is available to U.S. university scientists for research on nematode control in fruits and vegetables in Honduras, Guatemala and/or Haiti.
This call for pre-proposals comes from the Horticulture Innovation Lab, a program led by UC Davis with funding from the U.S. Agency for International Development. The Horticulture Innovation Lab builds international partnerships for fruit and vegetable research to improve livelihoods in developing countries. Continue reading

University of Georgia plant pathologist Phil Brannen is concerned that Georgia peach growers can’t tell the difference between phony peach disease and weevil or nematode damage. A consequence could be that farmers unnecessarily destroy trees and potential fruit.
Phony peach disease, nematodes and weevil damage stunt tree growth, but farmers take different management steps to treat the problems. Continue reading

Unlike pigweeds or plant bugs, nematodes are an out-of-sight, out-of-mind pest. Left untreated, however, this parasitic organism in the roots of a cotton plant can substantially reduce cotton yield. Resistant cotton varieties are becoming more critical in combatting this pest.
In west Texas, variety choice is more important than chemical control of nematodes because variety response is more consistent year after year than chemical response, according to Terry Wheeler, Texas A&M University plant pathologist. “Root-knot nematode occurs in about 40 percent of our cotton acreage, and reniform occurs in less than 1 percent. Our resistant cotton varieties are resistant to root-knot. Continue reading
