Growers use it against \u003cstrong\u003ethrip larvae, fungus gnats and their larvae, root aphid, silverbacks and springtails\u003c\/strong\u003e. Because it is dusted rather than sprayed, it stays put and keeps working far longer than a wet application in a warm grow room, forming a treated layer over the top of pots, trays and media where the next generation would otherwise emerge. Straightforward to apply and economical over a full cycle.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTargets soil-stage pests\u003c\/strong\u003e - thrip larvae, fungus gnat larvae, root aphid and springtails all pupate or feed at media level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLonger persistence\u003c\/strong\u003e - a dry dust does not evaporate off like a foliar spray, so a single application keeps working.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePyrethrin active\u003c\/strong\u003e - a well-established insecticidal chemistry with fast knockdown on contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaks the life cycle\u003c\/strong\u003e - treating the surface stops emerging adults before they can lay the next batch of eggs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple application\u003c\/strong\u003e - dust the top of the media, no mixing, no sprayer to clean afterwards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhere Sprays Struggle and Dust Gets Through\u003c\/h3\u003e\u003cp\u003eHalf the pests that ruin an indoor crop spend their vulnerable stages in the top centimetre of the medium, not on the foliage. You can spray leaves every week and still watch fungus gnats multiply, because the larvae are below the surface chewing roots. Treating the media surface attacks the part of the life cycle that foliar work misses, and a powder holds its position through watering cycles and airflow far better than a wet residue.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDust a light, even layer over the surface of the growing medium.\u003c\/li\u003e\n\u003cli\u003eTreat the tops of all pots, trays and any exposed media in the room at the same time.\u003c\/li\u003e\n\u003cli\u003eReapply after heavy top-watering or when monitoring traps show fresh activity.\u003c\/li\u003e\n\u003cli\u003eWear gloves and a dust mask while applying, and keep the room unoccupied until the dust settles.\u003c\/li\u003e\n\u003cli\u003eAlways read and follow the manufacturer label before use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFormat\u003c\/th\u003e\n\u003ctd\u003eDusting powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eActive chemistry\u003c\/th\u003e\n\u003ctd\u003ePyrethrins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTarget pests\u003c\/th\u003e\n\u003ctd\u003eThrip larvae, fungus gnats and larvae, root aphid, silverbacks, springtails\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eDust over the surface of growing media\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDelivery restriction\u003c\/th\u003e\n\u003ctd\u003eMainland UK only - cannot be sent to UK offshore destinations or Ireland under IMDG rules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Agrothrin","offers":[{"title":"Default Title","offer_id":53446972309770,"sku":null,"price":6.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/agrothrin.jpg?v=1785325215","url":"https:\/\/hydrocropshop.co.uk\/products\/agrothrin-dusting-powder","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
