Review: Very Effective Plant Protection - I've been having issues with spider mites on an indoor garden. I've tried multiple organic & DIY solutions which helped but never really eradicated them even accounting for egg hatch cycle & dormant time. I'd have to do multiple applications every 1-2 weeks to keep them at bay. So it was worth trying Crop Defender. I used one application of Crop Defender at the 'elimination' concentration level (vs preventative). It's now been over two weeks and no signs of any spider mites or other pests. That's a big win for protecting the plants from pests but also fungus/mildew. While the bottle is small (8 oz), it's concentrated & diluted in water so will last lots applications making the price worth the cost. It sprayed easily from a 1/2 gal hand held sprayer. Any remaining solution can be saved for the next application according to the instructions on the bottle (though probably won't be as effective over a long storage period of time). All the ingredients are organic making it safe to use for people & pets. Very happy to have finally got the upper hand on the spider mites.
Review: good - works beautifully
