Pulse electric field (PEF) employs bursts of high-voltage electricity to inactive microorganisms. Primarily used in the food industry, some researchers have reported promising results in nematode and plant disease control (Riga et al. 2020). We are collaborating with Lisi Global to adapt an existing technology for a new use in the ornamental nursery industry.
Testing tolerance with Marengo

Herbicide’s label allows growers to experiment with various plants and levels Herbicides are an important weed control method in container-grown ornamental plants. Knowledge of crop tolerance to herbicides is essential for a safe and effective weed control program. Tolerance to a specific herbicide application method depends on the crop species and the cultivar. Thus, developing […]

Researchers ‘go to the mats’ to test various control products By Marcelo L Moretti and David King Nostoc are cyanobacteria colonies that can grow where abundant moisture is available. These bacteria form continuous colonies that resemble mats covering gravel, plastic, concrete, or flat surfaces. Nostoc grow during the spring and summer and create a slippery […]

Weeds can become herbicide-resistant, but there are strategies to counteract it Evidently we hate weeds. The US Environmental Protection Agency (EPA) reports that expenditures on herbicides consistently accounted for the largest portion of total world pesticide expenditures at approximately 45 percent, followed by insecticides, fungicides, and other pesticides. Amazingly, in 2012, U.S. expenditures accounted for […]
