Pair of studies offers evidence into "superweed's" defensive tactics, strategy
FAYETTEVILLE, Ark. — A study of the effects of mowing on a common weed has found that what doesn't kill you can make you stronger.
A study published in Nature's Scientific Reports has found that frequent mowing of Solanum elaeagnifolium may help create a “superweed.”
Solanum elaeagnifolium — also known as silverleaf nightshade — can be found from south Texas to South Africa and Greece, infesting fields and soaking up valuable nutrients intended for cash crops. The weed with purple flowers – sometimes white and light purple – has prickly...

Herbicides are an important tool for the management of weeds in crops but an overreliance on herbicides for weed management has accelerated the development of herbicide-resistant weed biotypes. Staying ahead of the biology of herbicide resistance requires a sound understanding of the process and the other tools that are available to manage weeds. To help, we recently added several new resources on the WSU Wheat and Small Grains website about the ever-evolving topic of herbicide resistance. You may want to check them out:

Broomrapes (Orobanche and Phelipanche spp.) are obligate plant parasites with a broad range of agricultural crop hosts. In non-parasitic plant species, seeds generally initiate germination when exposed to favorable conditions of temperature, humidity, oxygen, and, occasionally, light. However, for obligate parasitic plants like broomrapes, a chemical signal from the host plant is essential. Germination of broomrape can only occur under appropriate soil conditions and when the seed receives a strigolactone chemical signal released from the roots of a suitable host. Strigolactones (SLs) are carotenoid-derived hormones that play a crucial role in various aspects of plant growth and development. Fertilizers can regulate...

Rely® 280 Herbicide Available for Use in California Avocado Groves
The California Department of Pesticide Regulation (DPR) has approved the herbicide Rely® 280 (glufosinate-ammonium) for use in avocado groves in California. Rely® 280 is a post-emergence broad-spectrum herbicide for use against broadleaf and grassy weeds. Glufosinate-ammonium is an excellent alternative to glyphosate, especially for those weeds that have developed glyphosate resistance.
The California Avocado Commission provided funding for Dr. Peggy Mauk, extension professor for subtropical horticulture at the University of California, Riverside, to conduct efficacy trials with...
