Arber Organic Fungicide Concentrate for Indoor & Outdoor Plants, 16 oz

This is a heck of a deal a 2 pack insecticide and fungicide. At some point you're going to need both of them. The insecticide comes in an 8 oz bottle you use 2 tbsp per gallon of water and spray it on your plants every two weeks, this bottle will make up to 8 gallons. The fungicide also is in 8 oz bottle & you use one tablespoon per gallon of water also spray every 2 weeks & it makes 8 gallons. These two may be mixed together safely. The Insecticide kills most common insects and a complete list is on the information sheet or on the bottle. Information on what the fungicide kills is also on the bottle. I do want to point out that this does NOT kill the Japanese Beetle. The Japanese Beetle is a very destructive bug, and it needs to have at least neem oil or pyrethrins applied. For all the other insects that's listed, the affectedness of this product is great, doesn't have any odor is easy to apply and if you want to use your hose end sprayer just follow the instructions on your device or use a gallon pressure container.

My experience of why I use and recommend Arber: As summer heat builds my insectaries in city pickers under my elevated grow beds in my greenhouse full of herbs and flowers hide in the foliage and stop keeping the white flies in check. I barely brush leaves and white flies are everywhere in my vegetable garden like a white cloud swarming at me. So I tried Arber after reading about it being organic; how it works, which made sense to me. It worked even on the extreme infestation. I sprayed double strength every five days at dusk and it was rewarding to see the population decrease. After the third treatment the population was reduced so they would not attack me if I brushed a plant so I harvested my crops and bagged the spent plants. I sprayed the surfaces of the grow beds, the soil and greenhouse surfaces with Arber. I hung yellow traps. I wheeled out the insectaries to the patio away from the rest of my garden outside. In days additional beneficial insects from my yard swarmed the plants and helped my beneficial insects in cooler temperatures to decrease the white flies. The small birds snacked on the whiteflies too. Meanwhile I cleaned and disinfected my greenhouse from top to bottom and cleaned the surfaces of the garden beds and the Trex floor. I drenched the soil with Arber. I checked the yellow traps and placed new ones after each treatment during the entire process and after the cleanup no white flies found on the traps. I waited a month and my insectaries healthy growing and a few white flies so I sprayed them because Arber didn’t hurt my beneficial insects or bees or red wigglers. I brought the city pickers back in the greenhouse and it was cooler so I planted my cold season crops of broccoli, peas, carrots, collards and red norland potatoes. I use Arber in my preventative measures to prevent a future outbreak of white flies. I spray every two weeks with 1 ounce per gallon of filtered water. I maintain healthy beneficial insects in city pickers to attract pests to the city pickers so the beneficial insects can dine. The flowers provide nectar to feed them too. I hang a yellow sticky trap so I can monitor and regularly inspect my plants. I use Nemaknights which has worked great to keep fungus gnats and thrips away. I will continue to use Arber in my greenhouse garden and if I inspect yellow traps in my basement grow room and see a bug I will use it there. In the grow room Nemaknights in the soil kept moist and in hydroponic reservoir has kept bugs at zero. I have a picture of last yellow trap hung in August after completing extensive treatment and I caught a few beneficial insects and a couple of fungus gnats that gave up on the beds. No bugs added in over a month- win win!

I have 57 houseplants and I had been battling fungus gnats for years. I tried pretty much every solution I could find, nematodes (mosquito bits), diatomaceous earth, gnat traps, bottom watering, natural sprays, essential oils, you name it. ("Mozzie tea" definitely helped but it was very annoying to brew in the quantities I needed and it never actually eliminated the problem.) This Arber Organic Insecticide & Fungicide combo is the first thing that truly worked for me. I use it every month or so, just by mixing a couple capfuls into my watering can. Incredibly easy. I still use yellow sticky traps to monitor which plants might need an extra treatment since the gnats sometimes attempt a comeback, but they’ve never gotten out of hand since I started using these. I now have a subscription (delivers every 3 months). It’s not the cheapest product, but after everything else I tried, given ease of use and effectiveness, it is 100% worth it. No more gnats flying in my face! If you have a fungus gnat problem and feel like you’ve tried everything, give this a shot. Takes time and regular use, but it works.

It's fairly gentle on my plants and I've had no issues with any leaf burn. I've used it to get rid of spider mites mostly, though the mites still seem to come back a month later. It's not that great on fungus gnats, mosquito bits work better than anything else on the market. Unfortunately I had to stop using it as a spray. Even in distilled water, it goes "fungal" and grows mold or some sort of scum which turns into chunks, if you leave it for more than a week in the bottle. Even my watering cans end up with this weird scum. This will then clog up a sprayer. (I ruined a really good continuous mister.) Now I use a different product to mix as a spray and this product to water with so that you get the soil pets and the leaf pests. The only other alternative would be that you have to mix, spray and then pour back into the watering can. Dropped off a star for that.

You need to try this if you’re sick and tired of fungus gnats!! I didn’t want to try the beneficial nematodes or any live bugs to try and solve my fungus gnat problem so I tried this and I am so so happy I did. It takes a few weeks of dedication. I have over 150+ indoor houseplants and with 2 bottles of this I was able to treat them all 2 times. I just follow the instructions and add it to water, I also added plant food to the same water, and I watered all my plants with the mixture. I feel like it has done my plants so many wonders. Some plants I had never looked great until I did this and it’s probably because it kills other bugs not just gnats so I probably had another pest issue that I didn’t even know about. I recommend trying this before anything harsher. I will say that I had 5 plants that were big problems and everytime I watered them like 10+ gnats fly out of the soil so for those plants I did the treatment 2x and I still had 1-3 flies come out so instead of doing it a third time I actually just changed out the soil and threw out the old soil, it’s for sure filled with gnat larva you cant see. I still have some gnats around the house but before it was like CONSTANT swatting and now I see a couple here and there. I may do a third treatment to everything and I may continue this just for preventative care but it lowered my problem by 90%!

I spent a fortune investing in these proiducts. The 4 for indoor use I have gone through many many bottles, prob 6 bottles total over 6-7 months. These products actually INCREASE gnats! Not decrease. They LOVE these products! I have over 70 houseplants. I have NEVER had a problem until I started using these products and now I have gnats everwhere and my yellow traps are COVERED everytime I water and this has been for weeks now. I emailed the company and got literally NO help. They insinuated that I am watereing too much and that is drawing the gnats. I really liked that these products were non-toxic BUT I used the products as diurected on a 12' diffenbachia that acquired mealy bugs AFTER I started using these products and these products killed it. I would'nt reccommend any of them. If I could give lees than a 1, I would. Here's a pic of the diffenbacia before this product was used on it. Now it's dead.

Works fast and can be used when it’s hot (unlike neem oil). Easy to mix and measure

Nicely packaged set does not seem to effect the grasshoppers one bit
