| description | For the development of ragweed control strategies, it is necessary to know its morphology and
flowering. In the suburban area studied most ragweed bushes reach a height of up to 1.50 m and
ramifications up to third order. Therefore, plant sizes reflect a medium growth. The number and
maximum lengths to which male inflorescences reach in August reveal the huge amount of pollen that
unmowed ragweed populations can provide. The dimorphism for feminine inflorescences is observed.
Most plants have only sessile groups. If they have both types of inflorescences, the number of sessile
groups is higher than the pedunculated ones. Due to climatic changes feminine flowers appear two
weeks later than two decades ago. These appear in mid-August at the level of the last two ramifications.
In order to prevent maximum flowering - for significantly reduce the amount of pollen in the air and
the amount of seeds -ragweed must be mowed twice in the climatic zone of Bihor County. For start in
the last days of July or the first days of August. To further reduce seeds production should also be
mowed in the first half of September. |
