Barriers to Foliar Penetration and Uptake of Herbicides
نویسنده
چکیده
To be effective, herbicides must enter the plant. This process can occur very quickly or very slowly, depending on the herbicide, formulation, plant, and environmental conditions. For foliar applied (postemergence) herbicides, penetration and uptake can occur through cracks in the leaf surface, stomatal cavities, or by diffusion through the cuticle. Other surface features of the leaf such as trichomes (hairs and glands) can greatly influence herbicide uptake.

The aim of this paper is to review the current knowledge on the uptake of mineral nutrients from foliar fertilization. Despite many studies carried out on mineral nutrient absorption by leaf tissues, many aspects of foliar fertilization are still unknown. At present, it is believed that such fertilization of plants is a valuable complement to the application of nutrients to the soil. Foliar fer...

One criterion of the effectiveness of nutritional sprays is the rate at which the foliar applied nutrients are absorbed by the leaf and translocated to other plant parts including the roots. Two distinct but not easily separated processes, absorption and transport, are involved. Initial penetration most likely involves passage through the cuticle and epidermal cells (17, 20); stomata may also p...

Poaceous weeds are prolific and competitive in winter crops, but they are more insidious in wheat due to their similar morphology and growing requirements. Herbicides are effective and efficient tools of weed management, however, they are vulnerable to resistance, and herbicides with different modes of action might check the dominance of a particular weed flora. The current study was undertaken...
