Barriers to Foliar Penetration and Uptake of Herbicides
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 tr...
متن کاملFoliar Diseases Affected by Residue
residues on the soil surface to retard soil erosion, insulate the soil, and conserve soil moisture. This residue consists of leaves, leaf sheaths, ear husks, and stalks of corn that decompose very slowly on the soil surface. The relationship of surface residue to corn diseases can be divided into two categories: (1) a source of inoculum of disease-causing organisms, and (2) environment modifica...
متن کاملVaried Responses of Black Gram (vigna Mungo) to Certain Foliar Applied Chemicals and Plant Growth Regulators
The studies on growth regulation in black gram cv. ADT (Aduthurai) 5 exhibited significant changes in growth, physiology and yield due to chemicals and plant growth regulators. Foliar application of NAA @ 40ppm at pre-flowering stage influenced growth characteristics by showing increased plant height, more number of branches, higher leaf area index and leaf area duration. But, with regard to ph...
متن کاملEffect of Foliar Spray of Chemicals on Flowering and Fruiting in Litchi
Bihar is known as hub of litchi production not only in India but also in the world due to its quality fruit. Entire country people desire to taste this fascinating fruit having unique fragrance and high demand during the season. The plant is highly specific to climatic condition and soil requirement and probably due to which its cultivation is restricted to the few countries in the world. Fruit...
متن کاملCell Penetration by Acids
Measurements of the penetration of tissue from Chromodoris zebra are believed to show that a determining factor in penetration involves the establishment of a critical pH (near 3.5) in relation to superficial cell proteins. The rapidity with which this state is produced depends upon acid strength, and upon some property of the acid influencing the speed of absorption; hence it is necessary to c...
