Keen'- the silvery stippled areas are thrip damage,... (the ragged holes are slug/snail damage, as you know, which can occur anywhere on the leaves and stems, BTW,... they feed with a rasping, rough tongue, so the damage they make is tell-tale, and they can attack a leaf from any angle)... thrips have piercing mouth parts, and like to stab and stab away sucking up juices, little bastards! They are highly mobile, adults can fly, and often leave the scene of the crime... sizes are very small, but not mite-small.. this dash would be a good sized thrip (-).... adults and larvae feed on the top and bottoms of leaves; eggs are laid in/on the plant; larvae pupate in the soil, but don't feed during this life stage.... Treatments become trickier as you go deeper into blooming,.. neem (raw first press seed oil type is best) will work, but I don't like the residue it leaves behind, and if mixed improperly, to concentrated, it can burn leaves, damage pistils, etc.,... I'm an outdoor grower, and thrips are ubiquitous! (along with leaf hoppers and aphids)... I've had excellent results with products that have Spinosad in it; several brands have it in their line-up... are you stateside? If so, horti-stores will carry something likely, or even Home Depot (Capt'n Jacks Dead Bug).... It leaves minimal residue, has zero impact on the plant, and is fairly broad spectrum killing power... it's a neurotoxin derived from an obscure bacterium... don't let that term freak you out, mate... even pyrethrum is a neurotoxin, made from chrysanthemums,... as mentioned, thrips are around
always, so you'll have to retreat occasionally, and inspect often! There are several other products that will do the job too... Azamax has a great rep',...*** So, pick a weapon,.. alas, too late to skip the neem, but that's good to have around anyway... someplace here, there's a good article about the various benefits of pure neem oil, beyond pest control...*** ..sticky traps kinda cut both ways,... yellow and blue attract several vermin bugs, but not like a magnet!..some will still take to the plants... they're generally better for just seeing what's snooping around the plants, and get an idea about the population size in that area,... Ag' pro's put these out all over for this very purpose,... *** Ah! just saw the product link-- not in the States... still, you can get spinosad products via that source,...look it up, or visit a horti-store if you have one around, or even just call garden centers locally... it's not an uncommon product... :ama: kick some buggy ass mate!
