New Virus likely culprit of colony collapse disorder in bees!
Comments (2)Seems likely, but don't count other options out just yet. Earlier in the year the media was claiming a new cause every other week....See MoreMosaic Virus question and other leaf virus?
Comments (2)Mosaic virus is rarely, if ever, fatal,in its self. It can weaken plants,so that they are attacked by other pathogens.The plants also can become such poor perfomers that they will be discarded. Some varieties have much more resistance than others,and will grow and bloom quite well,while the insects transfer the disease from it to other plants.The other plants may not do so well. GW owns posted poctures, so I have them elswhere. They also won't allow url links to the site or mention of competitors. If you input Mosaic virus , TMV or Hippeastrum Mosaic virus to a search engine,there is much tu be learned. Del...See MoreTomato-killing virus makes its appearance in California
Comments (6)That isn't good news, but seed companies are isolating tomato varieties that are resistant to the virus. Those in areas that already are threatened by the virus are working on the problem. Planting squash as a trap crop seems to help (see the link at the bottom). I've seen only one site that says you have to kill the pests that appear on trap crops (for anything), but that makes sense. If they aren't killed, then they'll lay over during the winter in huge numbers (they're incredibly prolific), nourished by the trap crop, and return in even greater numbers than the original infestation. There are several articles about whitefly control that you can google. All that I've seen recommend chemical sprays, which will kill beneficial insects, too. Here is a link that might be useful: Squash as a trap crop...See MoreCanna Virus Resistance
Comments (2)Ontac55, Thanks for posting and glad you are able to grow your Canna Musaefolia free of virus symptoms. The Musaefolia group of canna cultivars (Banana Cannas) are considered to be hybrid cultivars (not a species) such as ‘Musaefolia Hybrida’, 'Musaefolia Rubra’, 'Musaefolia Grande’ along with several other cultivars. Roughly 15/20 years ago when the canna virus first began to be more widely recognized many breeders sought to breed cultivars that seemed to be resistant (viral symptom free for most of the growing cycle). Resistance is usually considered a good thing but in the long term it has likely contributed to the widespread transmission of the disease. Viral resistance tends to be subjective in cannas. We often find growing location, temperature etc. produces plant growth that allows the plant to grow faster than the viral load; hence we get few if any viral symptoms. This resistance certainly varies between cultivars and where they may be growing. The positive side is that you are able to grow a great canna. The negative side is IF it does carry one of the canna viruses it can and likely will be transmitted (Typhoid Mary). If possible consider posting a photo. We might be able to I.D. the one you grow.
