Description

Steinernema feltiae are beneficial nematodes used to control fungus gnats and western flower thrips in the soil. Nematodes are safe for plants, people and pets and are an organic solution in place of harmful pesticides. S. feltiae are active in cooler weather and will survive and infect hosts in temperatures as low as 50°F.

Life Cycle

A complete life cycle takes 12 to 15 days at room temperature. Media temperatures should be above 50°F but not more than 88°F. Optimum media temperatures are between 60-70F. The nematodes enter the insect pest through body openings. Once inside they reproduce and release a symbiotic bacterium which is toxic to the host. The pests are killed within a few days and a second generation of infective juvenile nematodes exit the host and begin the cycle again. Use beneficial nematodes as part of an IPM program.

Entomopathogenic nematodes are supplied as infective juveniles, which are usually applied as a soil drench. Not all nematodes are alike. They specialize in which pests they attack and kill and are effective at different temperatures. 

Application Rates

Beneficial nematodes come in two forms. Sponges that are pre-inoculated with infective juveniles in quantities of 1 million, 6 million and 24 million. Generally, in a greenhouse setting, apply these beneficial nematodes at a rate of 1 million per 1,000 sq. ft. The sponge product has a completely unique application rate as the bacterial level is much higher because they are produced in vivo. 

Sponges - Nematodes from Sierra Biological are packed on a sponge of pure cellulose wood fiber that is hydrated with water for shipping. The sponges do not go into the crop, only the nematodes, once they have been mixed with water. 

Trays - contain 50 million or 250 million. Release every 2-3 weeks at a rate of 50 million/1100 sq. ft. or every 4-6 weeks at a rate of 50 million/550 sq. ft.  Use 30-50 gallons of water/1000 sq. ft. for applications onto soil or growing media. Some of these are certified organic. 

Instructions for Use

Apply nematodes with a sprayer, injector, hose end sprayer or even a watering can. Plug trays can be dipped in a nematode solution. If using an injector, set the dilution to 1:100. It is important to remove all filters or screens (50 mesh or finer) in any spray lines so that the nematodes can pass through unimpeded and undamaged.

Keep spray pressure below 300 psi. For every square foot you will need .66 gallons of water as the carrier. Saturate soil or potting media to a depth of 2". See Nematode Tech Sheet for further information. Broad spectrum pest control without toxic chemicals. Shipped fresh and quality guaranteed.

Amazon Melatonin? Amazing!
These work as well or better than some of the more expensive ones my wife usually gets. They don't dissolve in your mouth and they arent gummies. No extra sugars involved. Puts me to sleep quite well and allows me to stay asleep. No bad taste, no weird dreams. No side effects. Absolute gem of a find on Amazon. Great price for a great night sleep.

"Take this sinus infection!"
Size: 100 Count (Pack of 1)
I am a chronic sufferer of bacterial sinus infection. Ask me why, and I can give you some long winded explanation about a slightly deviated septum and sinus design, and a slew of other stuff that I've read and heard from my doctor. Bottom line, both you and I don't care the reasoning, but rather, preventative care. I can tell you that these Elderberry capsules help. If I get "that feeling" like a sinus infection is impending, I'll start popping two of these twice a day. 9 times out of 10, I can stave off the infection from grabbing a foothold in my sinuses long enough to let my immune system kick it completely out (without antibiotics and/or steroids). Does it help get rid of a sinus infection already in place?: inconclusive from my experience. Once I have a sinus infection, it takes about the same amount of time to get rid of it whether or not I'm taking it. Maybe I get rid of it a day soon, but statistically that's probably considered to be "noise in the data". Does it work for flu and other viral colds? I can't tell you that. I know that bacterial sinus infections can be precipitated by viral infections, but excluding bacterial sinus infection, I don't get sick. I've had the flu maybe twice in the last 20 years. Bottom line I have no experience with regard to using this to fight flu. Can't hurt to try though (I don't think you can OD on berries easily, could be wrong though). Does it have any other benefits? I don't know, maybe. Again I can only speak from experience. I take them, it staves off a sinus infection. I get that there are a lot of other beneficial claims about elderberry, but I have personally never noticed/experienced them. Is this just another homeopathic snake oil? No. While I agree that there are a lot of homeopathic "remedies" out there that don't work and are probably just a placebo effect, there are also ones out there that work. Heck, I've experienced allergic reactions to homeopathic remedies that landed me in worse trouble than before. Elderberry is a homeopathic remedy that works for me. Will it work for you? Maybe, maybe not, every body is different, and it could be that my body utilizes it due to a deficiency of something that elderberry has. Summary (tl;dr): Get it and try the bottle once. You can take it all the time, but I find it sufficient to take them when I feel a sinus infection coming on (I mean, who *wants* to take a bunch of pills at breakfast). Berry form is probably preferable, but the capsules are convenient and store for long periods of time without getting mildew-y. The price is right, it staves off sinus infections, and probably works for staving off other colds as well. Can't hurt to find out if your body responds to it.

Highly recommended!
Size: 100 Count (Pack of 1)
Sometimes these can be a bit challenging to find in my local pharmacy. I like the price and the quality. As a senior citizen, I like to give my immune system a boost from time to time. I'm not convinced of the benefits, but I figure I can't go wrong by trying these.
