Agronomic research on hemp Cannabis sativa L. Powdery mildews, black mildews, and rusts are caused by high-visibility fungi, but rarely cause serious problems McPartland Usually, they are applied in a manner similar to chemical herbicides hence called bioherbicides by periodic dispersals of distinct doses of the virulent inoculum [ 3743 ].

The gene involved has a pleiotropic effect on plant yields, it decreases biomass, fiber and seed production. Farmers may misinterpret symptoms as mineral deficiencies or drought, mysteriously arising despite adequate nutrients and moisture.
The hemp mozaic virus has been described on fiber cultivars in Europe and drug cultivars in Pakistan. Conflict of Interests The authors declare that there is no conflict of interests regarding the publication of this paper.
The wide host range, prolific growth, and ability to produce persistant sclerotia contribute to the large economic losses associated with the pathogen. However, the diversity among isolates could not be related with host and geographic origin.
The fungus produces small tan to dark-brown or black spherical sclerotia and survives over a wide range of pH 1.
Symptoms were described as a gray leaf mosaics. Competitive replacement of parthenium can be achieved by planting plants like Cassia sericea, C. Effects of inbreeding on some major characteristics of hemp. Chlorotic areas soon develop into a series of interveinal yellow streaks or chevron-stripes.
