Herbivore damage to sunflowers (Helianthus annuus L.) in the Czech Republic
Original language description
The numbers of large wild herbivores are rising in the Czech Republic, leading to increased grazing pressure on agricultural crops, including the sunflower (Helianthus annuus L.), which is highly sensitive to grazing. In this study, we aim to estimate the amount of damage to sunflower crops in the Czech Republic, experimentally evaluate the effects of grazing on sunflower development and yield and their response to given types of damage, and propose a procedure for quantifying damage caused to sunflower crops. Our results indicate that most sunflowers damaged below the cotyledon at any stage of growth died or failed to yield achenes, while those damaged above the cotyledon were better able to regenerate and produce some form of harvest. In most cases, plants damaged at 11 cm height (growth stage BBCH 10-12) were able to increase growth intensity, replace damaged tissue and make up for any loss. In later growth stages, this ability progressively decreased. Plants damaged at 15 cm (BBCH 14-16), for example, produced just 14% of achievable production. On the other hand, we observed a 10% yield increase in undamaged plants when competitive neighbours were removed. Overall, we estimate total damage to sunflower achene production caused by herbivores in the Czech Republic at 16%.
