Development of pyrimethanil as a postharvest fungicide  Pyrimethanil (PENBOTECTM) is a modern and specific anilinopyrimidine fungicide which was developed for postharvest uses in citrus and pome fruit. Due to its high efficacy o­n Penicillium italicum, P. digitatum, P. expansum and Botrytis cinerea, the most important storage diseases of citrus and pome fruit are controlled. Besides, interesting side effects are discovered o­n secondary pests as phlyctaena vagabunda o­n apple.

Evidence is obtained for a preventive, curative and anti-sporulant acitvity. Pyrimethanil is active o­n strains which were shown to be insensitive for the currently used fungicides as thiabendazole (Penicillium spp. and Botrytis) and imazalil (Penicillium digitatum). The compound can be used in different ways as aqueous (drencher, dip, CDA, NRS, in line spraying) or wax (storage and pack) applications. Tank mix compatibility, cultivar selectivity, optimal dose rates and its relation with fruit residue will be discussed. Possibilities for implementation of pyrimethanil in postharvest anti-resistance strategies will be explained.

After more than 20 years of practicing the existing fungicides, pyrimethanil will be a valuable tool in controlling postharvest storage diseases due its new mode of action, its high biological efficacy, its low risk profile and the possibility to implement this fungicide in most of the current application technologies.
