The effects of organic fertiliser MV-BV on tea shoot growth and population density ofgreen leafhopper (Empoasca flavescens Fabr.) and thrips (Physothrips setiventris Bagn.) werestudied in Phu Tho province, during spring season of 2010. As a consequence, populationdynamics of green leafhopper and thrips under the application of the organic fertiliseremerged earlier and increased more quickly. In addition, the length of tea shoots underorganic fertiliser had a direct correlation with the population density of green leafhopper (Y =2,545X - 2,392) and thrips (Y = 1.2517X -1.8115). We recommend that farmers should applythe organic fertiliser in combination with chemical fertilisers in order to enhance tea yieldsand pest control.
