Trifecta Crop Control Super Concentrate | 16 oz

This stuff is legit a plant saver. I was getting wrecked by spider mites and powdery mildew, and traditional stuff either didn't work or was super sketchy to use on my veggies. Enter Trifecta. It smells a bit strong (that essential oil blend—thyme, garlic, clove, etc.), but honestly, it’s worth it. It's natural and non-toxic, which is a HUGE plus for my indoor garden and stuff I actually eat. It acts as a preventative and a treatment. Mixed up a batch (super easy, just follow the directions) and sprayed my affected plants. Within a couple of days, the aphids were basically gone, and the mildew dried right up. I did have to reapply a couple of times for the really stubborn mites, but they eventually bounced. Just a heads-up: spray when your lights are off or at sundown to avoid leaf burn. It’s not an instant kill-all, but it absolutely manages the situation effectively. A little bottle goes a long way. If you want a safe, effective, all-in-one solution for common plant problems, this is a solid buy. Highly recommend!

It seemed to help prevent new black spot.

I grow veggies and herbs indoors, and insect infestations aren't normally a problem. I grow most of my plants from seed, but unfortunately bought some pineapple sage plants from a vendor that came complete with spider mites. By the time I saw the telltale signs of the webbing and browning leaves, the mites had spread to some of my other plants - tomatoes and peppers. Initially, I noticed the leaves on my cherry tomato and pepper plants were turning yellow, then brown, and then falling off. At first, I thought I was watering too little or too much, as this will cause leaves to turn yellow. Being careful with watering, the problem was still not resolved, so I thought it might be some kind of fungal infection. After buying and using a fungal spray for a while with no improvement, I finally examined damaged leaves with a magnifying glass. Upon examination, I saw tiny white spots on the underside of the leaves and what looked like tiny bits of webbing. These mites are so small, you need a magnifying glass to see them. Once you realize you have them, it takes time and diligence to get rid of them. I initially bought the quart spray bottle, and, of course, this wasn't enough. I have since bought 2 of the 1 gallon refill bottles to refill the spray bottle. The reason for the 4 star rating is that this spray is very expensive when using it on a number of plants. It does kill the spider mites, but it does not kill the eggs. So, whether you are trying to get rid of spider mites or another insect infestation, you need to learn the life cycle of the pest you are dealing with. In my case, dealing with white spider mites, they have a life span of only 2 to 4 weeks, it can takes only 3 days for eggs to hatch and a female can reach full development in 5 days. A female mite can lay 20 eggs per day, so one female can lay quite a few eggs in her short lifetime. The directions on this insecticide says to spray every 3 days. Judging from what I found on the life cycle of spider mites, this gives eggs more time to hatch and develop since they are all doing their thing every day and not necessarily on the same day. In my opinion, for spider mites, you would need to spray every day to kill the mites as they hatch and not give them a chance to lay more eggs. To spray less often will control them, but it will not eliminate them. As mentioned above, you need to learn the life cycle of the pest you are dealing with to eliminate it. This spray does kill the living pests, but it does not kill the eggs. If used outdoors, this spray may help to control pests, but I seriously doubt it would eliminate them. Although this spray is organic and does kill the pests stated, it is much to expensive to use for an outdoor application I guess the cost of this spray has to be weighed on how much you want to save your plants. I have used this spray on pepper plants, tomato plants and a couple of sage plants. With persistent spraying, I have been able to eliminate the mites on my plants. Granted, this has been costly, but it has saved my plants. Incidentally, I did save all of my tomato and pepper plants with persistent spraying of this product. Sadly, I can never be sure they are gone as even one live might can start another infestation. My plants are now healthy, but I continue to spray regularly and check the underside of leaves with a magnifying glass. I would recommend this spray for indoor plants or small applications. I hope this review was helpful for you. I will update this review if my opinion changes.

Works so well. Don't bother with cheaper alternatives. Just get this!

The price for this is insane for how poorly it worked. I would have to spray this daily. Ultimately, it did not do the trick.

My dad asked me to order this for him and he liked it. Says it works great for his garden outside

Seems to work.

Did nothing for catapilers

First off item arrived from USA to UK in six days way ahead of the 2 week delivery expectation. Secondly this product worked really well on the red spider mite that had attacked my prized flowers. A few mist sprays over three days worked a charm. I used a ratio of 1:63 (Trifecta : water).
