Benefits of Micronised Sulphur on Red Spiders, Fungal Diseases and the Negative Effect of Strong Insecticides and Pesticides on the Chlorophyll and Yield of Tea Crop

摘要

To maintain the healthy condition of the tea plant and to maintain the production of reasonable quantity of tea crop are the actual aim of the tea planters. There are many internal and external factors for the reduction of tea crops and among those factors the attack of insects and pests are one of the major factors for the reduction of tea crop. The tea planters used to apply the different types of hard insecticides and hard pesticides to control the attack of insects and pests and to free the tea plants from the attack of harmful insects and pests. If the tea planters think properly then it appears that the protection of roots, stem, and leaf of the tea plant means the maintenance of entire system of the tea plant or tea bushes. It is very much clear to the tea planters that the protection or saving of the three parts of tea plant means to allow the tea plant to make Photosynthesis and other physiological functions in normal condition. If the Photosynthesis is hampered then all the functions of tea plant will be disturbed, because the photosynthesis is the important physiological process by which the food of tea plant is made.
