Weed control and response of yellow and white popcorn hybrids to herbicides

Microbial Weed Control and Microbial Herbicides

Microbial weed control represents an innovative means to manage troublesome weeds and utilize the naturally occurring biological herbicides produced by soil microorganisms. These compounds kill or hinder the growth of weeds so that beneficial plant species can gain a competitive advantage. The vast diversity of microorganisms in our environment is largely untapped, and the potential discovery a...

Glyphosate-Resistant Weed Control and Soybean Injury in Response to Different PPO-Inhibiting Herbicides

In Nebraska, 5-enolpyruvyl shikimate-3-phosphate synthase (EPSPS) as well as acetolactate synthase (ALS)-inhibitor-resistant weeds occur in many soybean fields where herbicides from these modes-of-action have been frequently used in the past. Currently, the protoporphyrinogen oxidase (PPO)-inhibitors are the only effective herbicides for POST control of both glyphosateand ALS-inhibitor-resistan...

Weed Control Efficacy and Citrus Response to Flazasulfuron Applied Alone or in Combination with Other Herbicides

Field experiments were conducted to evaluate the phytotoxicity of flazasulfuron on citrus species and efficacy on weeds when applied alone or in combination with other herbicides. Grapefruit was the most sensitive and tangerine was the least sensitive to flazasulfuron. Injury to grapefruit was 70% with the application of flazasulfuron at 0.20 kg a.i. ha at 60 DAT and was reduced (5%) when flaza...

Weed Control and the Use of Herbicides in Sesame Production

Synergy between Synthetic and Microbial Herbicides for Weed Control

Synthetic herbicides have been investigated as tools to synergize mycoherbicides (fungal bioherbicides) for improved efficacy or management of hard-to-control weed problems. Herbicides may weaken weeds and impair their defence systems, thus making weeds more vulnerable to mycoherbicide infection. Despite many positive results, the practical value of synergy remains elusive. This review will dis...
