Does time of protective procedure and genotype of chamomile affect yield?
Summary Objective: Chamomile plants (Chamomilla recutita L. Rausch) are often attacked by pests, which usually cause the decrease of raw material yield and its quality. The objects of field trial were two chamomile cultivars: Złoty Łan (4n) and Promyk (2n) cultivated under organic regime. The aim of this study was to evaluate of impact of the spinosad treatment and its time of application on two chamomile cultivars: cv. Promyk – 2n and cv. Złoty Łan – 4n exposed to insect pests. Methods: The first treatment with spinosad as a preventative control (P) was performed in the early phase of plant development (seven leaves). Intervention (I) treatment was made in green bud phase. In both terms of observation insect pests were observed and collected. In each spraying application of 0.06 g of spinosad per 1 liter of water was used. Results: Spinosad was able to limit the number of pest population and finally increased yielding of the treated cultivars as compared to the untreated plants. Time of spinosad application for cv. Złoty Łan plants was not statistically siginificant, although was more effective for the preventative treatment of cv. Promyk in the increasing of the plant biomass (283.8 g · $ m^{−2} $) and seed (32 g · $ m^{−2} $) yields than intervention. Conclusion: Protection treatment with spinosad might be recommended in chamomile cultivation and it is more effective than intervention in diploid cultivar which begin blooming earlier than tetraploid. Essential oil content was not related with protection treatment for diploid cultivar, although intervention in tetraploid cultivar caused higher content of oil..
