Abstract:

Trichoderma harzianum (T39), prepared as a wettable powder (Trichodex), was compared with conventional fungicides (vinclozolin, iprodione, diethofencarb + carbendazim and tebuconazole + dichlofluanid) for control of Botrytis cinerea on greenhouse grown tomatoes, cucumbers and strawberries and in vineyards. In most cases, T. harzianum alone provided effective control, but did not always control B. cinerea on strawberries. Tank mixes of the biocontrol agent with dicarboximide fungicides were effective for control of grey mould in all crops. Alternation of Trichodex with dicarboximide fungicides or with diethofencarb + carbendazim generally resulted in a level of control similar to that obtained with the standard fungicides. The alternating programme achieved a reduction in fungicide residues in the fruits and the surrounding ecosystem, whilst the population of B. cinerea was exposed to less fungicide and is therefore less likely to develop resistance to them.
