The cannabis aphid is a pest aphid found on the leaves and stems of cannabis. Aphids have "piercing-sucking" mouthparts to feed on plant fluids. When aphids occur in high numbers, their feeding can stress plants and cause wilting, yellowing and other damage. Cannabis aphids are also potential vectors of plant pathogens.
The weather this fall has been ideal for development of molds (like Botrytis) in the tight colas of the hemp plant. The alternating cool and moist weather followed by a few clear days of moderate temperatures have been perfect for the moisture-loving fungus. Which translates to bad news for the growers, who depend on the flowers for their CBD-related products.
