Latest / Hydroponics Daily / Spider Mites - Control
Transcript
- 0:00Welcome back to the Hydroponics Daily. Today we're going to talk about how can
- 0:03you control red spider mites, the supervillain of the hydroponic world.
- 0:08So first thing to look at is an integrated pest management approach.
- 0:13So don't just rely on one particular method.
- 0:16Making sure that you use a variety of methods will increase your chances of success dramatically.
- 0:21The first one is making sure your temperatures are not too high.
- 0:25Spider mites thrive in high temperatures they
- 0:29have a preference for humidity but high temperatures is their key thing
- 0:31they will propagate far far faster when it's
- 0:34the temperatures are high and later on in the growing season you'll start to
- 0:37see them in the uk red spider mites were not
- 0:40an issue outdoors until the
- 0:43last few years with climate change so normally it was just a greenhouse pest
- 0:48but now you'll see them even in outdoor crops which is a shame it seems to be
- 0:52that and they would die off during the winter whereas spider mites tend to stay
- 0:56around even if dormant now so normally they would need to be transferred.
- 1:01So that for grow rooms that means that there's going to be a
- 1:04bigger population outside to potentially come inside even
- 1:07in areas where there wouldn't be traditionally any spider mites so temperature
- 1:10is a big thing you can control them with chemicals what we
- 1:13call miticides and there are a number of synthetic chemicals
- 1:16on the market however there might not be any authorized for your
- 1:19particular crop and they can
- 1:23have some can be very very potent chemicals because
- 1:26they're not insecticides so they can i think
- 1:30spiders are more closely related to humans so they're often they're like they're
- 1:33like nerve toxins and things like that so you have to be careful you can.
- 1:36Use natural extracts and soap we recommend dr
- 1:39hydrospidamite it's a very pungent natural extract
- 1:42product and has good effect
- 1:45if used as an integrated pest management biological control
- 1:48you can buy lots are predatory mites so you can buy mites that
- 1:52eat your mites you can buy other types
- 1:55of insect of insects yeah or my predatory
- 1:58mites are not insects but you can buy insects that will eat your
- 2:01spider mites with various degrees of success i'm
- 2:05not a big fan of ladybirds i don't think they do much but predatory mites
- 2:08are really good and will will devour spider mites
- 2:12to the point where they can actually wipe out the whole population quarantine
- 2:15is cannot be emphasized enough and
- 2:18is not conducted well enough by hydroponic growers especially
- 2:21of larger plants quarantine is
- 2:25essential keep your plants that you're bringing in your cuttings away from the
- 2:30plants you've got in your grow room already even if you're setting up a new
- 2:32grow keep them in it quarantined away from where you're going to put them because
- 2:36there will be spider mites and and even more so for thrips which can live as pupae.
- 2:42In the soil or actually they lay their eggs inside the leaf so quarantine is
- 2:48essential for them at least with spider mites you can sort of inspect them to
- 2:52check there's no spider mites on and no eggs on the surface or the lower surface
- 2:57of the leaf but these things won't germinate and won't.
- 3:01Emerge unless you keep them warm so keep get you get your
- 3:04new cuttings put them somewhere nice and warm and then monitor them
- 3:07for a few days to make sure there's no pest and disease on them before you
- 3:10put them into your grow room and then as i say my mantra
- 3:13is don't water your plants every day but do monitor them for
- 3:16pest and disease every day check on on the underside of
- 3:19the leaves as many as you can and always use a hand
- 3:22lens this is a times 10 hand lens with both uv
- 3:26and led and that's really good for
- 3:29finding really small spider mites you can buy these from us at utreema in the
- 3:33uk and just monitor your crop daily if you and that's not just so you can find
- 3:40it don't put your head in the sand because once an infestation has taken hold
- 3:45it is far far harder to control it
- 3:48doesn't matter if it's a pest disease a weed or anything it's just
- 3:51so much more harder to control it so if you find it when
- 3:54there's one or two plant pests on your plants then you
- 3:57can stand a good chance of controlling it if you start to see
- 3:59the spider mints balling up on the end of the leaves producing webs
- 4:03then you stand a far less
- 4:05chance of success if you see a few webs on your plants you
- 4:08think oh that's that's probably just a spider it's probably not a spider mite
- 4:12you're kidding yourself it's spider mites get control of it now before it gets
- 4:18any worse and that's my number one tip for hydroponic growers if you can control
- 4:22pest and disease in hydroponics you're three quarters is the way there.
- 4:27So get control of red spider mites or spider mites, two spotted spider mites,
- 4:33and you're on through a winner. That's been Hydroponic Daily for today.
