This research was conducted at Finca Santa Martha to the application of salicylic acid,
ascorbic acid, dulcamara extract and mix them to control downy mildew ( Peronospora
pulverulenta) in the cultivation of (Gypsophila paniculata) variety Party Time.
8 treatments were evaluated during the crop phenological stages such as induction,
elongation and flowering. We utilized an experimental design with 3 replications DBCA
was evaluated in incidence and severity.
Results and discussion.
The best treatments T1 and T2 are salicylic acid and ascorbic acid has the best rates for
benefit-cost and because they produce longer stems, but not heavy and the plants
became infected. It is therefore concluded that the best treatment is Salicylic Acid T2
because there was no percentage of re-inoculation of spores of the agent (Peronospora
pulverulenta) as happened with T1 ascorbic acid.
We recommend using gypsophila in growing culture under similar conditions Salicylic
Acid T2. |
