Can some kind person PLEASE PM me where to get Met 52? Would appreciate it so much.
First got these suckers 3 years ago. Took me 3 months to figure out what the problem was. Hit the vegging plants with Bayer Complete. Instant recovery on about 80%, dead RA's everywhere. Did not see a sign for 1 year with excellent harvests.
Then they came back. Bayer had no effect anymore. Stepped up to Criterion 75 WSP. Same as Merit but far cheaper. Major improvement but bugs kept returning. I use 0.5 grams per gallon which is FAR over the recommended, although nothing in flower. I live in a medical state and supply to many dispensaries where medicine is tested for harmful substances. Passed with flying colors every time.
Aphids definately build up a resistance to IMID. Started with recommended, then 0.25 per gallon, now 0.5 per gallon. This rate holds them in check with no signs in flower but does not eliminate them entirely.
I tried
Acephate. ABSOLUTELY no effect. The bugs made a comeback with weekly applications given. Imid worked far far better as it holds them in check.
I tried Excite R on its own. Exactly the same as Evergreen 60-6. Knocks them down but not enough to grow a problem free plant through flower.
Have not tried predatory bugs. Never had them work on other pests.
Recently I ordered some Verticillium Lecanni. They have had excellent results in Europe for greenhouse management of aphids. Have not used any yet. The problem is it is $50 for 1 kg. Dosage is 20 grams per gallon. Yeah $1 per gallon.
Botaniguard is about 0.70 cents per gallon. Both of those do not seem very cost effective.
My plan of attack, as none of the previous methods have shown to work completelyon their own.
In Veg
0.5 grams per gallon Criterion 75 every 2 water.
2 ml per gallon Excite R every water.
In Flower
2 ml per gallon Excite R every week in flower till week 4.
As you can see, this gets expensive FAST. My watering requires about 3-400 gallons per week.
Criterion 75. $65 for 180 grams = 18 Cents per Gallon
Excite R $70 for 1 pint = 14 Cent per Galon
So that is 32 cents per gallon or about $80-100 a week on pesticides alone.
If i add the fungicides it will go up to $4-500 per week. I am still deciding if I should make that investment in the hopes that this added will eliminate them completely, or just focus on control and not elimination.
In other words, these fucking bugs SUCK.
