The results showed that seed germination percentage, shoot length, root length and number of leaves was significantly (p≤0.05) increased with all the treatments. Captan (0.5%) was more effective in comparison with Captan (0.3%) and seed germination, shoot length, root length and number of leaves was gradually increased with increase of the doses of fungicides.

Thus, this work aimed to evaluate Varoviga® and Bayvarol® acaricides under the Egyptian conditions compared to formic acid. Sixteen honeybee colonies were used and divided into four groups 4 colonies/each group: first group as control, sec­ond group treated with Bayvarol acaricide, colonies were treated with Varoviga acaricide as third group, and colonies treated with formic acid as fourth group. Results showed that, formic acid had the major significant effect on varroa mites, followed by Bayvarol then Varoviga acaricides with no significant difference between them.  Moreover, the largest increase in honey store areas were found in the colonies treated with formic acid followed by Varoviga and Bayvarol acaricides, with all treatments leading to an increase in brood area without significant variations between them. No chemical residues were present in honey and wax samples that obtained from treated colonies. Regarding the financial coast, Varoviga appears to be an ideal alternative to formic acid, especially when it is not possible to use formic acid.
