First it gets drenched in seedling stage, then foliage every 4 weeks so the plant itself is the holder of the fight. Bugs eat some and get, well here's a quote "When the microscopic spores of the fungus come into contact with the body of an insect host, they germinate, penetrate the cuticle, and grow inside, killing the insect within a matter of days".I would guess they will climb when the pressure goes up. That bav bas stuff sounds interesting. I wonder how it works exactly?
Last two seasons my plants got hit heavy with what I think were mites so I tried it per Carmens suggestion and there's been only the slightest chews here and there so far. I'd be deep into a Safers soap foliar regimen to fight them by now! It costs is the downside but this should last for a few seasons if it keeps. Not unreasonable if they finish clean. Im thinking of bud worms dying before becoming a rot issue maybe too! We're going to have to watch that. If it's true, it'll be so good for this part of the world!
