Bentazon mixtures to control weeds in rice

Distribution and Effects of Bentazon in Crop Plants and Weeds

Bentazon, C 0 2-Assimilation, Inhibition of Photosynthesis, Photosystem 2-Herbicide, Shade-Type Adaptation of Chloroplasts The inhibition of photosynthetic C 0 2-assimilation and of the variable chlorophyll fluorescence as well as uptake and transport of 14C-labelled bentazon and the possibilities for a herbicideinduced shade-type modification of the photosynthetic apparatus were investigated i...

Integration of Allelopathy to Control Weeds in Rice

Rice (Oryza sative L.) is the main food crop in Asia and the staple food of the majority of the population in many regions of the world. The population pressure in rice-consuming countries demands that more attention be directed towards new approaches to sustainable rice produc‐ tion. Improvement of both crop quality and yield is an urgent task [1]. Optimally, rice yield improvement must be sou...

Managing Weeds of Rice in Africa

In sub-Saharan Africa (SSA), weeds are estimated to account for rice yield losses of at least 2.2 million tonnes (Mt) per year (Rodenburg and Johnson, 2009). Combined with costs of weed control, the financial losses easily surpass half the cost of current regional rice imports. If not controlled, weeds cause yield losses in the range of 28–74% in transplanted lowland rice, 28–89% in direct-seed...

Broadleaf Weed Control With Carfentrazone-Ethyl Tank Mixtures in Rice

Evaluation of Curvularia lunata as an Biological Control Agent in Major Weeds of Rice Paddies

Common water-plantain (Alisma plantago-aquatica L.), arrowhead (Sagitaria trifolia L.) and Echinochloa spp. (L.) are among the most important damaging weeds of rice paddies. In this research, Curvularia lunata (Waker) Boedijn was isolated from the said weeds. Then, its effect in different growth stages, i.e. seed, 2-3 leaf stage (seedling) and also in greenhouse conditions was examined in Alism...
