- Cotton resistant to root-knot nematodes unveiled
- Good yield potential with or without nematode pressure
- Texas-specific nematode problems
- When aldicarb was withdrawn from the U.S. market, cotton farmers began worrying about how they would deal with root-knot nematodes and other troublesome underground pests. Monsanto intorduces new variety resistance to root-knot nematodes.
- DP 1454NR is being targeted to two areas primarily – the area south of Lubbock around Seminole and Seagraves, Texas, and for the lower Southeast U.S. It is a full maturity variety.
Texas-specific nematode problems
One of the other new varieties, DP 1410 B2RF, is an early maturity variety for West Texas markets. Evaluated in the program as 13R315B2R2, it has shown exceptional storm resistance, as well as resistance to bacterial blight and tolerance to verticillium wilt. DP 1410 B2RF demonstrated very high yield potential and excellent fiber quality potential last season in West Texas NPE fields, growers said.
“DP 1410 B2RF did pretty well for us this year,” said Justin Garrett of Dumas, Texas. “It stripped great, and the maturity was right for us. It’s a short, compact plant compared to the other varieties. We had a lot of late rain and it stood out above the rest.
“It held tight enough in the bolls that cotton wasn’t falling out and stringy, yet it was still very easy to strip. It matured out all the way to the top of the plant and reacted very well to PGRs. I think it was actually a little better than DP 1321 B2RF, because it was so compact and matured out so nicely. I’m looking forward to seeing grade and yield comparisons. I tend to look at varieties that will do well in any given year. If it could do well in a year like 2013, I feel it can do well in any year,” Garrett said.
The third variety, DP 1441 RF, is a mid- to full-season variety for West Texas. Evaluated in the program as 12R244R2, this variety is an improvement over the popular Deltapine variety, DP 174 RF. It fits dryland and limited-water fields, much like 1044 B2RF, and is easy to manage, according to NPE farmers who evaluated it in 2013.
“This variety looked good in our irrigated NPE plot all season,” said Chad Brown of Lubbock, Texas. “I liked the way it grew. It was easy to manage, showed good storm proof and made a good yield average and good fiber quality. The turnout was 35.9 percent, and it went into the loan at around 55.08 cents.”
