Description
With the objectives of contributing to the development of an IPM program in the PAMAF 2034 “Improvement
greenhouse horticultural production in the Oeste region”, a greenhouse tomato Varieties Demonstration Field has
been accompanied belonging to the AGRO nº 4 project “Development of integrated production techniques for
protected and open-field vegetables in the Oeste region”.
The greenhouse, located in A-dos-Cunhados, is composed of a material structure of eight bodies with a lateral
and an overhead opening per body. The Autumn-Winter crop was evaluated in two distinct substrates: rock
wool and coconut fibre and comprised 45 varieties of medium and large “beef”, “cherry”, “bunch” and
“chucha” tomatoes. The culture presented the tripe Frankliniella occidentalis as its main enemy during the
installation phase. With the development of culture TSWV, bacterial, namely, Pseudomonas complex, leaf
worms (Autographa gamma, Chrysodeixis chalcites) and fruit worms (Helicoverpa armigera) development. Despite
the overhead opening, the structure showed insufficient venting capacity, which was aggravated by the
development of grey mould (Botrytis cinerea) and powdery mildew (Leveillula taurica, even thought the
adequate treatment, defoliation and pruning. The variety susceptibility to the main enemies is evaluated and
discussed.
