Cannabis is a crop gaining acres across the nation with more states legalizing its growth. Due to the demand of organic cannabis and cannabis related products, cannabis growers usually face problems with diseases like Powdery Mildew and Botrytis.
Powdery mildew is a widespread plant disease. Spores that spread the disease are in the air or on contaminated plants in the garden, spores can easily find its way to the cannabis crop. The disease thrives on warm dry climate yet outbreaks have also been reported past extended and humid winters. The disease can be observed as a white-coating on leaves and shoot tips if the infection is severe plants often cannot be saved. As cultural practices infected plants as well as wilting plants should be removed from the growing area to avoid disease dissemination. Infections that happen during the last few weeks of flowering can be managed until harvest specifically through the use of a good fungicide. Mother plants and cuttings should be treated preventively so that valuable genetics are not lost.
Powdery mildew is an aggressive disease and most of the time it’s complemented by attacks of Botrytis. Preventative programs with cultural practices as well as the inclusion of fungicides are strongly recommended. Fungicides are suggested to be included especially during crucial stages in the development of the plant. Corrective treatments might be also possible with the right product and application program yet the costs associated tend to be higher.
