TLDR
Prospects for biocontrol of B. cinerea in greenhouse vegetables appear good under a range of conditions, but regression analysis showed that high temperature during the day and high vapour pressure deficit during the night reduced biOControl efficacy.Abstract:
The efficacy of Trichoderma harzianum T39 and the yeasts Aureobasidium pullulans and Cryptococcus albidus against Botrytis cinerea in cucumber and tomato was compared with chemical control. Four experiments were conducted in cucumber grown under different climatic conditions in The Netherlands, and two experiments were done in tomato both in the Netherlands and in Israel. T. harzianum and A. pullulans showed the most consistent control of B. cinerea, reducing stem lesions and death of plants by 40–100% in most cases. Control of stem lesions and subsequent wilting was generally better than control of symptoms on fruits. In some cases, the biocontrol agents were more effective than the broad-spectrum fungicide tolylfluanid and the selective fungicide iprodione. The climatic conditions did not strongly influence the efficacy of the biocontrol agents, but regression analysis showed that high temperature during the day and high vapour pressure deficit during the night reduced biocontrol efficacy. From the results, prospects for biocontrol of B. cinerea in greenhouse vegetables appear good under a range of conditions.read more

A greenhouse without pesticides: fact or fantasy?
TL;DR: Integrated management of pests and diseases without conventional chemical pesticides is a goal that will be realised for most of the important vegetables in Europe within a decade, and is increasingly used in ornamentals.

Combining biocontrol agents to reduce the variability of biological control.
TL;DR: Application of both biocontrol agents resulted in better suppression of Botrytis cinerea, and also reduced the variability of disease control.

The beneficial effect of Trichoderma spp. on tomato is modulated by the plant genotype
TL;DR: It is demonstrated that genetic variability among wild and cultivated tomato lines affects the outcome of the interaction with two 'elite' biocontrol strains of T. atroviride and T. harzianum, and the ability of the plant to benefit from this symbiotic-like interaction can be genetically improved.

TL;DR: Three selected Trichoderma strains, namely T-39, T-161 and T-166, were evaluated in large-scale experiments using different timing application and dosage rates for reduction of strawberry anthracnose and grey mould and only a few treatments resulted in significant control of grey mould.
