Tomato ( Lycopersicon esculentum Mill., indeterminate F1- hybrid Alena) plants grown in a plastic greenhouse were used as a source of initial explants when more than 70% of the yield was harvested. Tomato micropropagation was communicated to be initiated from seedlings or young plants (Kartha, et al, 1977 Polevaya, et al, 1988) The possibility of micropropagation initiating from adult fruiting tomato plants was studied in our work. No off-type plants were observed among greenhouse-grown plants arised from micropropagated plantlets A full route from the initiation of flower raceme to the formation of mature fruits has been reproduced in vitro. That would include yarrow, dill, fennel, parsley, coriander, tansy, alyssum, butterfly weed, lemon balm, etc.Vegetative off-springs of adult tomato plants were maintained and propagated in vitro through microcutting for as little as two years. Plants withstand minor damage readily.īest thing you can do for your garden (along with composting) is to plant nectar bearing flowers to attract the beneficial insects, ladybugs, lacewings, tiny parasitic wasps, and others. What you want is a healthy eco-system where everything is in balance. If you could get rid of all the aphids, etc, then there would be nothing for the ladybugs and other beneficial insects to eat and they would go away. So you may be stressing more than you need to. They are susceptible to soapy water spray also.Īnd tomato plants are just naturally kind of hairy/ fuzzy.īut your plants look healthy and not showing any particular signs of damage. There are things called white flies that are small and white and will flutter up when disturbed, looking like a mini snow storm. I don't see much that looks like white flakes. It takes a whole ton of aphids to do significant damage to healthy plants. Otherwise a soapy water spray should get rid of them. A lot of times you can get rid of the aphids either by squishing them or just with a water spray from the hose. Your "little green insects" were probably aphids also. On the bottom picture, I can see some little darkish insects, maybe aphids. Once buried in moist soil, the primordia grow in to real roots, giving the plant a better root system. It is why we always tell people to bury tomato plants deep. In the middle picture, the little bumps on the stem are root primordia. What are these things and what is the best way to handle them? I'm in Charlotte NC if that makes any difference, and I'd really like to nip the problem in the bud before it gets out of control.Īny advice or suggestions are appreciated! It's been around 2 days since I noticed they had returned and I've sprayed twice, and so far nothing major has happened. I've sprayed them down with neem oil, hoping that it would get rid of them or prevent them from growing. They did show up on some of the others, but I was able to get rid of them one at a time basically (the plants were smaller so it was easier than it would be now). I lost one plant because it quickly turned into being covered with little green insects and I figured it was better to throw the whole thing away than risk contaminating all of the other plants. This is my first year growing veggies, mostly tomatoes, and so far everything's going well (as far as I can tell)Įarlier on, I had noticed some little white flake-like spots showing up on (not part of) my tomatoes.
