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...

ABSTRACT Analysis of images has been recently used in order to both assess seed quality and elucidate some aspects of seed physiology, including X-ray tests and other resources. The objective of this study was to examine whether the X-ray may be successfully used to detect physical abnormalities, and relate their occurrence with physiological potential of tetsukabuto type squash seeds. Fruits were harvested at different maturation stages (15, 30, 45, 60 and 75 days after anthesis - DAA) and temporarily or not stored for 20 days. Seeds were radiographed using an intensity of 25 kV for 40 seconds and then germinated under alternating temperatures of 20-30 ºC. After four and eight days, percentages of normal and abnormal seedlings and dead seeds were...
