Understanding the spectral characteristics of crops in response to stress caused by weeds is a basic step improving precision agricultural technologies that manage field. This research focused on competition between corn (Zea mays) and redroot pigweed (Amaranthus retroflexus), common weed strongly reduces yield. The aim this was characterize physiological changes occur during early growth becau...

Greenhouse studies were conducted to evaluate the effects of soil organic matter content and pH on initial residual weed control with flumioxazin by planting selected species in various lab-made field soils. Initial was determined seeds into soils treated (71 g ha−1). Seeds Echinochloa crus-galli (barnyard grass), Setaria faberi (giant foxtail), Amaranthus retroflexus (redroot pigweed), Abutilo...

Eighteen volatile monoterpenes, which are among the major constituents of essential oils from plants, were screened for phytotoxicity to several crop and weed species. Several monoterpenes containing an oxygen function severely inhibited germination of four different annual weeds while concurrently displaying little effect on soybean germination. Soybeans varied in their sensitivity to various ...

We compared photosynthesis and growth of Zea mays L (corn) and four weed species, Setaria viridis (L) Beauv (green foxtail), Echinochloa crus-galli (L) Beauv (barnyardgrass), Abutilon theophrasti Medic (velvetleaf), and Amaranthus retroflexus L (redroot pigweed), following foliar applications with atrazine, mesotrione, or a combination of atrazine and mesotrione in two greenhouse experiments. P...

Anaerobic soil disinfestation (ASD) is a promising alternative to chemical fumigation for controlling soilborne plant pathogens and weeds. This study investigated the impact of brewer’s spent grain (BSG), locally available carbon source, on various weed species oomycete pathogen Pythium irregulare in ASD. Two greenhouse studies were conducted using BSG yeast at full reduced rates completely ran...

This study identified the most effective methods for protecting sunflowers from weeds through treatment of crops with herbicides Euro Lightning, Lightning Plus and Express. These options provided substantial protection such as cursed thistle, field bindweed, yellow bristle grass, mustard, frost blite redroot pigweed. In fight against ragweed, excellent action herbicide Express good results. Var...
