Recent confirmation of dicamba-resistant kochia [Bassia scoparia (L.) A.J. Scott] in Alberta warrants investigation resistance to other commonly used synthetic auxin herbicides like fluroxypyr. A randomized-stratified survey 305 sites was conducted 2017 determine the status fluroxypyr-resistant kochia. Overall, 13% populations were fluroxypyr-resistant. Only 4% both fluroxypyr- and dicamba-resi...

A tanulmány 44 neofiton faj 272 új elterjedési adatát tartalmazza Magyarország területéről az elmúlt néhány évből. Először sikerült kimutatni Magyarországról Iris orientalis-t, melynek meghonosodott populációját találtuk kiszáradt, sztyeppesedő mocsárréten. közelmúltban megtelepedett, de vélhetően vasút mentén gyorsan terjedő lesz a Lepidium oblongum. Kerti szökevényként Buddleja davidii és Bro...
