Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Crop rotation and herbicide program effects on Palmer amaranth and common ragweed population growth rate

Crop, Forage &Turfgrass Management, Volume 11, Issue 1, June 2025.
Abstract The success of weed management decisions must be assessed not only in the short‐term within season but also in the long‐term over several seasons. This study investigated the effects of crop rotation and herbicide program structure on the population growth rates of Palmer amaranth (Amaranthus palmeri S.

Current and future management challenges for globally invasive grasses, with special reference to Echinochloa crus‐galli, Panicum capillare and Sorghum halepense

Weed Research, Volume 65, Issue 2, March/April 2025.
Abstract Without appropriate and ongoing management interventions, weeds will continue to economically and environmentally disadvantage agricultural and natural ecosystems. For these management strategies to have long‐term sustained success, they need to carefully consider the biological aspects of the targeted weed.

Study of photosynthesis process in the presence of low concentrations of clomazone herbicide in tobacco (Nicotiana tabacum) [PDF]

, 2013
The effect of chemical residues of clomazone on photosynthetic processes has been studiedby using several low concentrations of the herbicide (0, 1, 0.1, 0.01, 0.001, 0.0001 and 0.00001) µM and seedlings of two varieties of tobacco (Nicotiana tabacum

Ecotoxicological effects of commercial herbicides on the reproductive system of aquatic arthropod Limnocoris submontandoni (Hemiptera: Naucoridae)

Brazilian Journal of Biology, 2021
Worldwide, conventional agriculture makes extensive use of pesticides. Although the effects of herbicides are relatively well known in terms of environmental impacts on non-target organisms, there is very little scientific evidence regarding the impacts ...

Clomazone herbicide impairs bioenergetics in mitochondria isolated from the thorax of honey bees (Apis mellifera L.)

Brazilian Journal of Animal and Environmental Research
The excessive use of pesticides on crops has caused an increase in animal mortality, contamination of soil, water and food, in addition to being identified as one of the causes of death of bees. Despite being quite effective, the herbicide clomazone (CLZ)
