Abstract
The use of selected Trichoderma isolates with Pinus radiata in New Zealand forestry has improved health and vigour (by 10-20%) of seedlings and cuttings in containerised and soil bed nursery systems over the past 20 years. Nursery stock inoculated with a commercialised mixture of Trichoderma atroviride isolates (ABORGUARD) reduced losses from Armillaria disease (by between 25 and 50%) in forestry plantations in New Zealand. Using the same concept in Malaysia, Trichoderma cultures were isolated from a variety of healthy plant roots sampled in the Planted Forest Zone in Sarawak. From these isolates, inoculum of pure cultures and selected mixtures was grown for trials using Acacia seedlings at the Samarakan Nursery. The best Trichoderma treatments were selected after ten replicated trials (Aug 2008 - Aug 2009). These increased seedling growth and health and the proportion of seedlings meeting specification for planting out into the forest by 66%, compared with the standard nursery practice. These results were validated on a large scale in the nursery, with exactly the same benefits observed as in the trials. A new mass production facility for Trichoderma inoculum was designed and built and is capable of producing sufficient Trichoderma to treat the total nursery throughout of around 30 million plants per year. Trichoderma inoculum was mixed into the nursery substrate for growing the seedlings prior to seed sowing. The nursery standard practice has now been changed from the use of multiple fungicide sprays to a single Trichoderma application before sowing the Acacia mangium seed.
