Thrips eating my plants.

Post by Keeno »

Wassup GR420

In all my years growing the wonderful cannabis plant ive never had pest issues. This being my first full summer in a out building i should have suspected something to pop up and therefore been prepared for it. GMO noticed some damage in my diary to some leaves, he told be to get the loupe out, so i did....









Having never dealt with them i turned to gmo as he had noticed them, so if this dont work and he suddenly disappears he is banned :lol:.

Ive ordered the following 2 products along with enough of the yellow sticky fly paper to cover wembley twice:

Pyrethrum 5 EC




"Naturally occurring Pyrethrins are insecticides deriving from dried Chrysanthemum flowers that have been trusted through the ages for fast and effective pest control. Pyrethrum 5 EC finally gives indoor gardeners a safe way to harness the power of Pyrethrins whether youre growing edible or non-edible plants!

Just one of several exciting products to come from Agropharm, a leading name in professional pest control, Pyrethrum 5 EC targets an impressive array of insects including Aphids, Blackfly, Greenfly, Whitefly, Thrips and Spider Mites. By blanket spraying your plants with a solution made up from this concentrate, all unwanted visitors will quickly be destroyed and pleasingly no toxic residuals are left over in the aftermath! At a dilution rate of 4ml per 1 litre of water, this 100% natural foliar application offers tremendous value whether you select the 250mls or 1 litre size and also proves suitable for organics!"


Hotshot no pest strips



"Keep bugs where they belong: out of your home. The Hot Shot unscented hanging insect repellent kills flying and crawling insects with a penetrating, odorless vapor. Just hang or stand the strip up in attics, garages, storage areas and other spaces, including boats, RVs and cabins (when not in use).
Clean, Odorless Insect Protection
Kill flying and crawling bugs in attics, garages, storage spaces, boats, RVs, and cabins with Hot Shot No-Pest Strip. This hanging insect repellent uses advanced controlled-release technology to slowly diffuse a deep, penetrating vapor throughout the enclosed treatment space for up to four months. Its clean, odorless vapor is evenly distributed, killing both visible and hidden insects on contact and preventing new insect infestations. Because it continuously emits vapor, Hot Shot No-Pest Strip is designed to be used in areas occupied by people less than four hours per day, such as garages, attics, or sheds. You can also hang one in your vacation home, cabin, mobile home, or boat while it's not being used."



The hotshot strips are not available in the UK so will take some time to arrive, the EC5 should be here tomorrow. Ill hit the plants with a heavy foliar feed as soon as it arrives and also spray my entire groom down at the same time.

Ill update this thread as i deal with the little shits.
It's nice to be nice :Stoned:

Love the hotshot No pest strip. If you came across a good deal please let me know. I hate having to pay nearly Β£15 each.

STEPS ON APPLYING DE TO KILL THRIPS
Clean up any dead plant material on or around plants to prevent other varieties of insects that may cause harm to your plant. In my experience bugs that eat my plants are drawn to the dead plant material. So if you are greenhousing it this year, get your room cleaned and disinfected before you start really growing.
Apply Diatomaceous earth, in a visible fashion, to the entire plant and be sure to focus on tight areas or areas where plant foliage may be folded. Be sure to get the underside of the leaves
Apply a 1 inch think layer of DE on the grounds from the center stem out a few inches past the drip line of the plant. This step is super important to be sure we get any of the dormant nymphs that come to the ground to develop into adults. This action prevents the nymph from becoming an adult, where adults fly to the canopy and lay eggs.
As a prevention you may do this action every 2 weeks in your grow. But during an infestion its best to keep up on the application on a weekly basis.
Be sure to reapply after every rain or watering as DE will get washed away. Just be sure its visible, very important
Repeat steps 1-6 as needed throughout the growing season

The EC5 arrived yesterday, you think I could find my spray bottle....so 16 mile round trip up b and q for one this morning πŸ™ˆ, I got 2 as I'll loose or break one within 6 minutes.

I added 4ml per litre as recommended on the label and went to work. Strangely the critical were far more effected by the thrips. I found only a couple leaves on the AO affected. This could be down to the AO being from cut so much more woody stems, or many the little shits don't like orange as much as me πŸ˜‚.

As the critical are smaller I sprayed 500ml per plant, the AO got 1 litre per plant. Making sure I covered top and bottom of leaves, stems, all plant matter. I then sprayed both grooms with a full 3 litres each, every corner, under spill trays, pots. I raised the lights before hand and set both to 250w.

A little update,

I cut parts of the worst effected leaves off to give them a real good look through my loupe and not a single creepy crawly in sight. This EC5 gear seems to be spot on.

Well my happiness was shorted lived...

I noticed some more damage today. It's hard as the EC5 will mess a plant up so its difficult to see where the damage is coming from. I took a leaf off both critical and Agent orange and looked through a loupe....there were a few adults on there. No babies in sight so it looks like the first treatment is breaking the life cycle.

I popped to see GMO and he sent me home with some neem oil to go wiht my EC5. I proceed to foliar treat the plants with ec5 and then lost my shit and literally mopped the tent walls and floors with the neem oil. I then really lost my shit and mopped the garage floor with neem oil . So as it stands there isnt a surface out there that hasn't seen some form of pesticide .

The Agent orange seems to be handling the treatment much better. This could be that they are older or the fact they are clones so the stems are much harder. Unfortunately the critical has been stunted and mutated. I'm on a timeline as I need my whole out building clear of grow gear and plants later in the year, unfortunately I think this is the end for the critical.

These just turned up. They got a real strong vapour smell the minute you open the bags. I've put both in the ao tent and turned everything off so it's a sealed room. I'll leave it for 6 hours then fire it up.

Is it a slow release gas type that kills them or just sticky traps with a scent
