Tebuconazole effect over Penicillium sp. control during postharvest of citrus fruit in commercial conditionsnnnn

The main fungus which affects citrus fruit during its storage and marketing is Penicillium sp.
Packing houses apply different kinds of authorized fungicides once citrus fruit reaches their facilities.
The most widely used fungicide is Imazalil but its continuous use may cause an excess of residues, which may possibly be above commercial requirements, or it may lead to the development of resistance.
Therefore, there is a need to seek out new plant protection products, which include Tebuconazole, in order to use them as alternatives to those commonly used.
The following study was carried out to test the efficacy of a Tebuconazole formulation as a fungicide, which was used in an on-line application (1000 ppm a.i.) or mixed with wax (1000 ppm a.i.) and applied to several cultivars of citrus fruit previously inoculated with Penicillium digitatum and Penicillium italicum. This fruit was compared to fruit that had not been treated or had been treated with Imazalil.
The results show that the fungicidal effect of Tebuconazole against Penicillium sp. was similar to Imazalil in on-line applications and when mixed with wax.
Therefore, it can be concluded that Tebuconazole is a viable alternative to other plant protection products.
