Abstract
Trials for biological activity establishment of certain mineral and essential oils applied alone or in combination for control to green peach aphid (Myzus persicae Sulz.) in pepper cultivar ‘Stryama’ grown in greenhouses were conducted.
The chemical products Mospilan 20 SP 0.0125% and Karate max 0.025% are used for standards.
High efficacy similar to those standards included in the study showed the combination Mospilan 20 SP 0.009%+ Akarzin 0.25% (efficacy over 90%), the mineral oil Akarzin 0.4% used alone, as well as essential oils Turpentine 1% and Eucalyptus oil 1% (efficacy over 80%). According to three way factorial analysis of variance it was established that the sources of the variation: variants of treatment (A), days after treatment (B), years of the study (C) and interaction between the applied variants and years of study (A x C) have a significant effect of the variability and efficacy.
The power of the effect of the treated variants was pre-dominant (91.11%) while the power of the remaining considerable factors reached to 4.2% in total.
Good efficacy demonstrated from these oils gives us another alternative possibility to control green peach aphid density in greenhouse pepper production.
