You shouldn't have to use Neem Oil when growing outdoors unless your grow area receives no breeze and you aren't able to rinse the entire plant. Mites tend to be an indoor grow problem. If you suspect mites in your outdoor grow, give the leaves a good dousing of H2o before sunrise and/or turn a fan on them. BT is great. I use that too, but not for mites. I use them on catties.
Cold pressed neem oil is the one many proprietary formulas around that dilute the effectiveness of neem like soap and water added ensure you spray both sides of the plant neem is systemic, organic and good for molds and bugs of all types for your condition apply 2-3 times per week good luck
Looks like moths, caterpillars, slugs, snails or grasshoppers are dining on your plants. Been is great to kill and prevent mites and other pest but does nothing for the pest I listed. I use either BT or Spinosad mixed with neem or another insecticide for mites along with a squirt of dish soap. I spray my plants weekly if no signs of pest or every thread days if I have signs if pest. Mites and other pest can build a resistance to insecticide so it's important to rotate what you use for mites each treatment. I use the soap every time as it acts as an emulsion ( helps stick to the plants) and it also suffocates the mites. Sent from my iPhone using Grasscity Forum
