Mode Of Action:
Mycorrhizae are obligate and saprophytic in nature requiring a living host for their survival. Commonly divided into three major groups Ectomycorrhiza, Endomycorrhiza and Ectendomycorrhiza. Ectomycorrhiza and Endomycorrhiza are important in agriculture, fungi penetrate into the plant cells, producing balloon like vesicles. The structure of the arbuscules increase the contact surface between the hyphal and the cell cytoplasm to facilitate the transfer of nutrients between them and VAM fungi produce the glycoprotein glomalin which may be one of the major stores of carbon in the soil. VAM fungi enhances phosphate uptake and mobilize immobile micronutrients like Fe, Mn, Zn, Cu, Bo, Mo. Besides these it imparts resistance to plant against drought, soil borne fungal pathogens and nematodes. There is no septum in their hyphae. The fungi hyphae penetrate in to cortex layer of the root and form the hyphal organ “vesicles” and “arbusculus”. The interaction between VAM fungi and plants is generally mutualism based upon nutrient exchange.
Benefits To The Crop:
Improves plant root growth and development
Increases the uptake and mobilization of phosphate in all crops
Increases and facilitate nutrient and translocation from the soil and root cuticle parenchyma to xylem ,Phloem, elements like nitrogen, potassium, Iron, manganese, magnesium, copper, zinc, boron, sulphur and molybdenum
Effective in overcoming the stress condition like drought, disease incidence and deficiency of nutrients
Enhances product quality and increases immune power of the crop
VAM supplements root hair in water absorption hence prevents reduction in crop relative water content of cells and helps to overcome drought.
