The objective of this study was to compare FirstAct with several tank mix partners for efficacy in herbicide-tolerant grain sorghum. (quizalofop) alone or mixtures controlled Johnsongrass 94% more. However, mixing any broadleaf herbicide generally antagonistic Palmer amaranth control. Minor sorghum injury 5% less by four weeks after postemergence treatment. Sorghum yields increased all treatmen...

Eight species of the genus Cercospora from different localities in Northern provinces of Iran were obtained and examined during spring-autumn 2010. Cercospora acnidae (from Amaranthus chlorostachys var. chlorostachys), C. beticola (from Beta vulgaris), C. iridis (from Iris sp.), C. lactucae-sativae (from Lactuca sativa), C. mercurialis (from Mercurialis annua), C. sorghi (from Sorghum halepense...

This research was conducted to determine the efficacy of quizalofop (FirstAct) herbicide in herbicide-tolerant grain sorghum. FirstAct evaluated for and crop response Double Team (ACCase-tolerant) All herbicides controlled Palmer amaranth 90% or more volunteer corn 95% late season. Johnsongrass control 86 91%. Minor sorghum injury early season did not persist. Sorghum receiving postemergence yi...

Abstract The current study aimed to screen glyphosate-alternative weed control methods in three perennial crops Greece. Field trials were conducted and repeated (2018 2019 2020) a citrus orchard ( Citrus clementina Hort. ex Tan), an olive grove Olea europaea L.), vineyard Vitis vinifera L.) under the randomized complete block design (nine treatments, four blocks). Glyphosate was applied (720 g ...

Abstract The presence of a soil seedbank facilitates the persistence annual weed species in arable fields. Soil is replenished by many sources, but largest one seeds produced uncontrolled late-season escapes. estimation seed production potential from escapes may allow farmers to make appropriate management decisions minimize replenishment. objective this research was evaluate feasibility using ...

Element Stewardship Abstracts (ESAs) are prepared to provide The Nature Conservancy's Stewardship staff and other land managers with current management-related information on those species and communities that are most important to protect, or most important to control. The abstracts organize and summarize data from numerous sources including literature and researchers and managers actively wor...

Allelopathic effects of aqueous extract of rhizomes of  Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...

Accurate information on the spatial distribution of weeds is key to effective site-specific weed management and efficient sustainable use control measures. This work focuses early detection johnsongrass, common cocklebur velvetleaf present in a corn field using high resolution airborne hyperspectral imagery acquired when plants were four six leaf growth stage. Following appropriate radiometric ...
