Re: Variegation in Anthuriums ?

From: "Celeste Whitlow" politicalamazon at charter.net> on 2002.03.03 at 22:32:15(8241) The way I understand it, viruses in plants are vector borne. The vector for transmission of virus is, as mentioned, often chewing-type insects. However, another often overlooked route of virus transmission is the cutting done by humans with tainted pruners. So if one gets a plant with a virus, it is best to get rid of it immediately. I think also that it would be wise for the near future, after the plant was destroyed, to dip pruners or any other cutting instruments in alcohol inbetween working with each plant. I don't think there is a way to get rid of a virus in a plant. They don't make a plant antiviral treatment, to my knowledge. --Celeste +More ----- Original Message ----- To: "Multiple recipients of list AROID-L" Sent: Sunday, March 03, 2002 9:27 AM Subject: Re: Variegation in Anthuriums ? > > ----- Original Message ----- > From: > To: Multiple recipients of list AROID-L > Sent: Saturday, March 02, 2002 7:16 PM > Subject: Re: Variegation in Anthuriums ? > > > In a message dated Tue, 26 Feb 2002 4:51:13 PM Eastern Standard Time, > "Julius Boos" writes: > > > > I have also seen birds nest Anthuriums > > and another large leaf hybrid called 'Anth. lazaro' ex-tissue culture with > > dasheen mosiac virus.
