Abstract:
... Laboratory measurements of susceptibility to Bt toxins can be a poor indicator of the ability of an insect to survive on transgenic crops. We investigated the potential of using leaf tissue for evaluating heliothine susceptibilities to two dualgene Bt cottons, Gossypium hirsutum L. A preliminary study with different cotton leaf disk combinations was performed to determine the best procedure for us ...

Thirty-three field trials were conducted focused on Enlist cotton injury from glufosinate as affected by cotton growth stage, application rate, and single or sequential applications. Maximum injury from a single application of typical 1X (542 g ae ha⁻¹) and 2X use rates was 3 and 13%, re ...

Abstract:
... Cotton (Gossypium spp.), as the most important fiber and oilseed crop in the world, is extremely important for the industry. However, due to its indeterminate growth habit and complex branching system, massive labor costs are needed for shoot apex removal and branch pruning during cotton production. Therefore, it is very important to explore branch-controlling genes and genetically modify the bran ...
