Abstract
To the effective control of invasive weeds are essential to prevent establish, if has already happened obstacle to massive accumulation, and promoting the efficient and rapid eradication, if it is possible. The Woolly cupgrass (Eriochloa villosa /Thunb./ Kunth) belongs to weeds which “hard to control” especially in corn. One of the difficulties of effective control is the prolonged emergence causing avoidance of several individuals the contact with pre-emergent herbicides. Another problem arises due to the intensive use of post-emergence herbicide products with short duration of action. To optimalize of timing of treatment is essential for successful control of later emerging weeds. The recently established Woolly cupgrass in Hungary shows resistance or reduced susceptibility to substantial portion of herbicides used in corn. The data collected from small-plot trials demonstrates that application of sulfonylurea or selective monoctyledonous herbicides can be effective against the Woolly cupgrass.
Highlights
The number of weed species affect agricultural production is around 6700
The effectiveness of post-emergent herbicide treatments is shown in the Table 2
The most of herbicides which generally used in maize production reached weak or very poor rating
Summary
The number of weed species affect agricultural production is around 6700. About 200 weed species cause significant problems for crop production worldwide. The accumulation and spread of weeds highly affected by the effectiveness of applied weed control technology in a certain area. Increasing number of new weed species have appeared in Hungary such as Woolly cupgrass (Eriochloa villosa /Thunb./ Kunth). Changes in weed flora elements, appearance of new species can be influenced by: - changes in farming systems and tillage depth. These can highlight those weed species which are less tolerant for disturbances. - climate change contribution to increase frost-free periods resulting extension of growing season especially for the warm-loving weeds (Szőke, 2001) These can highlight those weed species which are less tolerant for disturbances. - introduction of non native species by seed, feed, and food trade, transport, stuck in vehicles etc). - climate change contribution to increase frost-free periods resulting extension of growing season especially for the warm-loving weeds (Szőke, 2001)
