Eric: the Merit 75 is systemic and extremely effective all by itself (and relatively non-toxic). Every 14 days for a couple of sprays and you are done. Why all the other stuff with it?I use a mixture, water, Neem, rubbing alcohol, Dr. Bonner's lavender oil soap, and for a kicker Merit 75! However, with mealies I only use this after I have removed those I see with alcohol on a Q-tip.
Any idea for European users?
[USER=8900]@emydura - over the summer, we had a pyracantha in a relatively secluded part of the yard become completely infested with mealies. They were so thick, the plant looked like it had been sprayed with the fake snow flocking stuff used for decoration. It was literally all white. Three, weekly treatments with Azamax eradicated them. One treatment got almost all, from a visual check perspective.
None, whatsoever - on paphs, phrags, phals, a couple of sarcos, and the small vandas, tolumnias, tillandsias and neoregelias on my “epiphyte tree”. I do always try to treat plants in the morning, so they can dry as the day warms.Just one more quick question. Have you noticed any sensitivities of Paphs to Azamax? I have a few multi-florals in bud at the moment.
Because I like the natural components also. BTW, if you think Merit is non-toxic, I think you better check again!Eric: the Merit 75 is systemic and extremely effective all by itself (and relatively non-toxic). Every 14 days for a couple of sprays and you are done. Why all the other stuff with it?
So no reactions to leaf burns or bud damage?
The key word was relatively.Because I like the natural components also. BTW, if you think Merit is non-toxic, I think you better check again!
Jeeze, microwaves plants to kill insects!!!The key word was relatively.
Always spray early in the day, before the plants have begun to warm up. It’s not guaranteed to be safe, but is the best bet.So with oils ------ not sure what the procedure is ----- such as to apply the oil and keep it out of the sun for 'X' days ...... followed by washing/wiping the leaves to get rid of residue oil before putting high light on them again.
Now Eric, be nice! Below you will see what the ratings mean, hence my "relatively" statement. Merit, Azamax and Neem are all in the "Caution" category. Yes, it's a chemical and not considered organic as Neem is, but that doesn't mean it's necessarily more dangerous in use. If I were going to consume it, clearly organic is better. But as far as application goes, the same precautions are recommended for each. Merit does not kill spider mites, and as was pointed out could allow an overrun of those if they are present, but I've found it to be very effective.Jeeze, microwaves plants to kill insects!!!
I tried to finish writing my post above (#21) to the end twice, both times something went wrong just before I could post it in its entirety. I actually decided to give up on it, and just leave it by that. But I just can't turn my back to a request from you, Chris! So here we go again:
As insecticides in Denmark and EU as such have at large been prohibited for common use by non-profesionals and have been restricted and highly regulated for use in farming, nurseries, etc., we have had to find new ways for fighting those ubiquitous little bug(ger)s!
I got the following advice from a very experienced and dedicated grower of Neofinetias. It is as cheap and easy to use as it is efficient. I even find it more effective than Calypso (Bayer), that was the most efficient insecticide allowed for hobby growers, before it was prohibited.
In a spray flask mix an emulsion of: 1 ltr. somewhat lukewarm water, 15 ml of unperfumed and uncoloured dishwashing liquid and 15-20 ml paraffin oil, normally used for lamp oil or barbecue lighter fluid (a high-burning kerosene fraction). In Denmark the latter, "tændvæske", can be bought cheaply in supermarkets.
Before use shake it dilligently - during use shake ever so often. Spray the leaves of the plants. Leave the plants to dry.
Plants with a risk for crown rot (fx. Phalaenopsis) or with areas especially susceptible for rot, I dry lightly with a piece of paper towel or with a cotton swab in these areas and then let them dry. If you grow the plants under conditions with better ventilation, than is possible for me, you might not need to dry them as I do.
Repeat the procedure every 5-7 days untill you have made sure the little blighters have gone to bug-heaven or bug-hell (the latter place is indeed where they belong!).
I know people are discussing the length of the hatching cycle of mealybugs, and its implication for treatment. Without having studied the question in detail I would consider 10 days a too long period to wait with the method, described here (as the chemical used is not a systemic remedy), but from an experiental point of view I would consider you on the safe side within the 7 days margin stipulated.
By the way the procedure also applies well in treating scale bugs and mite-infestations.
Best of luck with the crusade on mealy bugs and other like pests!
orchids.
For orchids growing out in the sun or gets a fair bit of power from the light into the oil regions on the leaf -------- the overheat can definitely
just received a small bottle of AzaMax and have query regarding the dosage. If I’m understanding I’m to use 2 tsp per gallon. If that is correct my small bottle will not last long at all!
Over the winter I will treat single plants with Isopropanol when I see mealies pop up.
In spring, when moisture isn't such a problem any more I will start to treat them with oil again. I've used it every 10-14 days. Maybe that's too long. So next time I will try to spray every 5 days. Fingers crossed!
Now Eric, be nice!
