Hybridized cotton reverses resistance of pink bollworm to Bt cotton

in Southwest Farm Press

Researchers with the University of Arizona and China discovered a surprising strategy to reverse pink bollworm resistance to genetically engineered cotton.

Cotton growers have been able to use genetically engineered cotton to fight the pink bollworm. This has happened as scientists have been able to produce pest-killing proteins from the widespread soil bacterium Bacillus thuringiensis, or Bt. Without adequate countermeasures, scientists have discovered that pests can quickly evolve resistance. Continue reading

Texas Psyllid Survey Team helps protect potato production

by Kay Ledbetter, Texas A&M AgriLife

Adult potato psyllids are testing positive in the Rio Grande Valley and Pearsall. That’s all potato growers need to know across Texas to start planning how to protect their crops.

Texas A&M AgriLife Research is at the forefront of the notification process in the battle against zebra chip of potato, a disease that once almost destroyed the potato industry in Texas. While the disease is not harmful to humans, the discoloration it causes results in discounts on potatoes going into the market. Continue reading

Weeds could develop resistance to dicamba in three generations

In Delta Farm Press

What happens if farmers follow the same practices they have when other new herbicide chemistries have come on the market over the last several decades?

If they’re not careful, they will simply replace one herbicide with another, as they did with Prowl and Treflan, ALS herbicides, glyphosate and most recently with PPO inhibitors such as Flextar and Reflex. Continue reading
