Onc sphacellatum x Oda 'Pacifica' Saved from virus.
Comments (5)I like your thinking. I'm motivated. At this point in time, space for orchids is at a premium. So my adjustment will be to have a double of selected plants only. With more growing space I would add to the selected list but continue to expand. If I had thousands of sq. ft. of growing space, I'd double them all. Another method of survival is to give the "double" to a capable grower with the understanding of the purpose. And reciprocate. And that is one of the many benefits of trading orchids. That just comes with the trade. We only trade divisions and keep the best plant......See MoreMottle Virus??!! :(
Comments (6)Hi, thanks for the response. I'll take it one by one: Virus seldom hits all plants. Those are only 3 of my 18, only that look kinda could-be-ill, others are just fine Not calcium deficiency. That would kill new leaves. What do you mean? For example this guy seems to have similar problem Suspect the regular doses of trace elements is excessive. Aight, I will cut back the ferts...also, I found somewhere it could be a water PH problem, since I did not test my water yet, that could be the case (will buy a tester asap) What rate does the package of 5-5-5 say to use? And how much are you adding every week? They say 15ml to 4litres of water and feed once in 2 weeks, I am giving them small doses (same concentration) once a week. Why are the plants indoors? That was only for the photos, they are normally outside on my windows (I live in a flat). However, some of the bigger plants tend to struggle with direct sunlight (windows are faced to east, so the sun is shining on them ~7am-12am), tilt drastically and seems to have little sunburns, but when they're on the window inside of the room, they seem fine. I also put the one looking the worst away from the others, inside, since I still dunno if it isn't a virus or something. Thanks again, I bought some Mg and Ca, so will feed it a little with this (can't do any harm, right?) I am also increasingly more suspecting it could be aphids, I noticed some tiny little black dots, so will get an magnifying glass and have a look....See MoreMite, Virus, or other Damage? (Not Pretty)
Comments (55)Nik - Glad to see your other thread got some traction and hopefully results! If you haven't cut off the distorted growth on your cacti, I would do so. The pests really like to hide in the crevices and even inside growth masses (often they have internal folds). Stush - Thanks for your input. Many mites are host-specific as you say. Eriophyid (Aloe mites) are probably the scariest thing I've ever dealt with. There don't really seem to be many success stories or solid advice out there, other than destroy/discard the plant immediately. Plantspace - Yay, thanks! It does appear very grim online and these plants were so hard to get. I couldn't give up on them so I did a crazy amount of research instead. Here is my Ultrasonic Cleaner. It's capacity is 600mL, which is a decent size for small plants. You can get bigger ones, but they cost more than $40. If you are curious, there was a really good study by the Agricultural Research Service, U.S. Department of Agriculture: Ultrasonic Treaments to Control Surface Pests of Fruit. The reason I went for ultrasonic miticide application are as follows: Ultrasound destroys mite tissues and kill them (10 minutes+ bath). Ultrasound knocks the mites off the plant and many of the eggs too. Full immersion of the plant in miticide ensures full coverage. Ultrasonic agitation enables the miticide to penetrate deeper into crevices where mites like to hide. Ultrasound cleans debris from the plant, making further close inspection easy. My ultrasonic miticide application method: Bare-root the affected plant. Put the plant upside-down in a small glass jar or beaker. This saves the amount of miticide necessary and keeps the main bath clean for other things (jewelery, etc.) Mix the miticide of choice in a separate container. Warm water is better along with a little surfactant or insecticidal soap. This improves cavitation significantly. Place the small jar with plant in the ultrasonic cleaner. Fill the small jar with miticide up to the bath fill line. Try to not have any bubbles in the leaves. Use a metal chopstick or similar to move the plant around. Fill the main bath portion with warm water. Make sure you don't fill too high or else the jar and plant will float up. Run the ultrasonic cleaner for 10 minutes for maximum effectiveness. Once done, set the plant to air-dry and then repot. Leave out of bright light for a week and then reinspect. The biggest risk that I was worried about was phytotoxic damage from the ultrasound to the plant. It was a non-issue. Based on scientific studies, the ultrasound does not penetrate deeply into the plant tissues so they are not damaged. In practicality, some of the finer root hairs are probably destroyed in the process, but overall I saw very little difference. The leaves all looked and grew fine after the ultrasonic treatments so I don't think there is much to worry about. The miticides I used were Avid, Bayer 3-in-1, and Schultz Insect Spray (Insecticidal Soap plus Pyrethrin). This was extremely effective. For future mite treatments, I would also consider Floramite and Sevin for rotational purposes. I have more import buys currently on their way. =) My biggest frustration with these plants is that I paid for phytosanitary inspection and certificate, yet the plants never came with the certificate and were not clean. So I am doubtful it was done properly. For any new additions, I always inspect carefully with a loupe (sometimes microscope) and quarantine if I am suspicious of anything. A watchful eye has been the most important asset of mine....See MoreWill microwaving kill the virus? Yes, I'm pretty cuckoo here.
Comments (33)greywings -- YES! Handle any 'valuable' mail w/actual *hands* in back hall, then wash said *hands*. We are not very 'computerized', so we do have some valuable mail. I my BCBS membership for Standard Plan F Saturday, twenty days after enrolling by phone. Once public health nurses would spread newspapers on a kitchen table for a home birth. Maybe that's not helpful against viruses... Maybe we should not continue to read our real newspaper at the breakfast table? DH will wear 'outside' shoes to the grocery. He will get paper bags at checkout, and place them on one kitchen counter at home. I wipe down cardboad/plastic out of the bags, then wipe down the countertop once paper bags are gone to the garage. I'm just using a mild bleach solution and cloth rags. Sufficient? My oncologist has eliminated a separate trip for blood draw ahead of office visit and chemo shot. One longer stay is considered better than two shorter ones. I might go to my car after lab and MD visit. There's usually a long wait for my Velcade shot to be prepared, based on lab report. Sorry to write so much. Maybe useful to others?...See More- 6 years ago
