Research Activities
- Herbicide-resistant ryegrass in the southern U.S.
- Analysis of genetic relationships between ryegrass (Lolium
spp.) biotypes and the spread of diclofop-resistant ryegrass
- Cross-resistance and multiple resistance patterns of diclofop-resistant
ryegrass
- Mechanisms of herbicide resistance
- Confirmation of resistance to diclofop or other herbicides as
service for wheat producers
- Weedy Rice (red rice, Oryza sativa L.)
- Morphological and genetic diversity of red rice populations in
Arkansas
- Comparative physiology between red rice and rice
- Gene flow between herbicide-resistant (Clearfield) rice and red
rice
- Flowering patterns of cultivated rice and red rice biotypes
- Background tolerance of red rice to herbicides
- Alternative herbicides and cultural practices for red rice management
- Longevity of red rice seed
- Barnyardgrass (Echinochloa crus-galli)
- Confirmation of resistance to propanil or quinclorac as service
for rice growers
- Cowpea (Vigna unguiculata)
- Natural tolerance to herbicides registered in field crops (soybean,
corn, rice, etc.) to obtain new clearances for additional herbicides in cowpea
production
- Spinach (Spinacea oleracea)
- Screening for possible herbicides in spinach
- Herbicides for minor use crops other than cowpea and spinach, including
southern greens (collard, kale, mustard, turnip greens); snapbeans; tomato;
cucurbits; sweet potato; and sweet sorghum. This is under the auspices
of the IR-4 program.
