Abstract: 

Root lesion nematode, Pratylenchus loosi, is one of the most important pests of tea plantations that causes severe damage to the mature tea plants. In order to reduce damage and nematode population on tea plants, organophosphate nematicides Rugby 10G (Cadusafos) and Nemacure 10G and EC400 (Fenamiphos) were tested each at two rates, under a complete Randomized Block Design in a time span of two years. The experiments were carried out in two different areas of tea plantation, Lashidan and Zomeidan in the north of Iran. Root and soilsamples were taken prior to application and two, fiveand nine months after applicationin the first year and two, six and thirteen months after application in the second year. The nematicides caused significant reduction of nematode populationsin the roots (in Farsi text) at all of the dosagesand all sampling intervals, the maximum reduction was obtained in the second year. The green leaf tea yield was significantly increased in plants treated with nematicides.
