Field bindweed (Convulus arvensis L.): Biology and control

Abstract

Field bindweed is a perennial herb with rhizomes belonging to the family of twining plants (Convolvulaceae). It propagates from the seed or vegetatively (from buds formed in the root whose cuttings have a great capacity of regeneration). Field bindweed is distributed all over the world. Due to its dual propagation this plant is classified into a group of very noxious and resistant weeds. As herbicides are not powerful enough in this weed control it is recommended to apply combined chemical and mechanical measures. The present study analyses the effect of primary tillage, crop rotation and crop density on the distribution of this weed species in the maize crop. Satisfactory results in the improvement of the crop status and this perennial species control can be achieved within the integrated weed management system, which means a particular field cropping system.

Poponac njivski (C. arvensis L.) je višegodišnja zeljasta biljka sa rizomima. Pripada familiji povijuša (Convolvulaceae). Razmnožava se semenom i vegetativno (pupoljcima obrazovanim na korenu, čije reznice imaju veliku moć regeneracije). Rasprostranjena je u celom svetu. Dvostruki način razmnožavanja poponca svrstava ovu vrstu u veoma štetne i otporne korove. Kako se slabije suzbija herbicidima, preporučuje se kombinovana primena hemijskih i mehaničkih mera. U radu se analizira uticaj osnovne obrade zemljišta, plodoreda i gustine useva na zastupljenost ove vrste u usevu kukuruza. U okviru integralnog sistema kontrole korova, koji podrazumeva određeni sistem gajenja useva, mogu se postići zadovoljavajući rezultati u poboljšanju stanja useva i kontroli ove višegodišnje vrste.
