While it's not great for cutting, narrowleaf zinnia doesn't need deadheading to keep blooming either. Zinnia (Zinnia) is a genus of plants in the family Asteraceae. Based on the highest similarity 97% at nucleotide and 99% at amino acid level and closest relationship with isolates of Zinnia leaf curl virus, the present study isolate was considered an isolate of Zinnia leaf curl virus. CAUSE: Nitrogen deficiency always affects the oldest (lowest) leaves first, because when new leaves aren't getting enough of the nutrient to sustain their growth, the plant redirects it from the existing leaves.

Ipatenco holds a bachelor's degree and a master's degree in education, both from the University of Denver. Severely affected leaves brown, dry, and become brittle. However, some of these tree varieties can be resistant to leaf curl. The degenerate primer pair PA /PB was used to amplify part of the intergenic region and AV2 gene of DNA-A like molecule (Xie et al., 2002). phylogenetic analysis confirmed the presence of Zinnia leaf curl virus on Zinnia elegans in the present study. SYMPTOMS: Lower leaves look yellow and become soft and curl inward, then turn brown and crispy before falling off completely.

By Marylee Gowans The treatment of leaf curl depends on the cause of the leaf curl. In peppers, it causes curling, rolling, puckering, blistering of the leaves and swelling of the veins ( Osaki and Inouye, 1981 ). This dislodges the aphids and rinses away their honeydew.
