Pest Factor in the Intensification of Teak Cultivation: A Global Assessment
Intensification of teak cultivation, both in terms of intensive management with high nutrients input and genetic selection for faster growth rate, and large-scale expansion of plantations into exotic locations are both recent phenomena. Limited empirical data as well as theoretical considerations show that both generate the risk of new pest problems. The well-known teak defoliator of Asia, which has been shown to rob native teak plantations of over 40 per cent of its potential volume increment, has not so far been recorded from Africa. In Australia and Latin America, although the insect is present, it is unknown as a pest of teak. But the situation changed when outbreaks appeared all of a sudden in plantations in Costa Rica in 1995 and Brazil in 1996. Theoretical considerations show that the extent of plantations is one among several factors that determine pest outbreaks in exotics. Unfortunately, the pest factor is not given due consideration in plantation planning and management. Even the growth assessment in the DANIDA International Teak Provenance Trial suffered from lack of insight into the geographical spread and seasonal dynamics of teak defoliator outbreaks. The threat and implications of pest outbreaks in the global expansion of teak plantations and their sustainability are assessed.
We are one and only high yielding tissue culture teak producers in India & abroad

Plantations that use best management practices can be 20 times more efficient, in terms of production, as compared to the natural forests.
