| ABSTRACT Anthracnose, one of the major diseases in the onion, is caused by the fungus Colletotrichum gloeosporioides f. sp. cepae. The main strategy for controlling this fungus is by the use of fungicide, with this technique being used on the majority of crops. Currently, methods of disease control are being studied that are less aggressive to the environment, with the use of essential oils proving to be an alternative. As such, the aim of this study was to evaluate the direct effect of the essential oils of basil (Ocimum basilicum), lemongrass (Cymbopogon citratus (DC) Stapf.), sage (Salvia officinalis), thyme (Thymus vulgaris) and citronella (Cymbopogon winterianus) as an alternative in the control of the fungus C. gloeosporioides f. sp. cepae, in... |

| The powdery mildew complex (Leveillula taurica and Erysiphe sp.) is one of the major factors limiting tomato (Solanum lycopersicum) production in the Azapa Valley, Chile. This problem is especially severe in the case of protected crops because the options for the treatment of these crops with chemical fungicides are limited. This study evaluated the effects of 0.5 and 1.0 kg100 L-1 Ospo-V55® and 10% raw cow's milk on tomato leaflets infected by powdery mildew complex. Ospo-V55®, with active ingredients consisting of 10% p/p of algae extract (IB-101) and 0.8% of microorganism concentrate, was evaluated in this study. Ospo-V55® contains flavonoids, alkaloids and phenols, oligo- and polysaccharides, 8.6% protein, 0.5% magnesium and trace amounts of... |
