pest control
 
Can I 7-Dust my Hops? My Cascade has small thin holes in its leaves like a bug has been there but I've searched the plant and see nothing! I have 7 other varieties and they are all fine..

As long as you do it early before flowering. Read the label and don't over apply.

I can't comment on hops specifically but I can vouch for 7 dust as an insecticide in general. Like stated above, follow the directions and apply as early as possible. It has kept my garden incredibly productive.

7-dust(not the band) 7-spray, lady bugs. anal retentive hops watching/bug sqashing. Piss on em, have ur neighbors dog piss on em. tons of solutions. However I used the 7 spray form last year before the ladybugs moved in and had good results, so i see no reason why the dust would not wor just as well.

I'm having almost the same issue, mostly with my Northern Brewer but now its starting to show up on my other hop plants as well. I found a product online called Liquid Ladybug but its pricey and I haven't been able to check and see if I can get it locally. I might go the 7 spray form until they get bigger and start flowering as I know I can get that at local stores.

Speaking of ladybugs...

I introduced ladybugs to deal with aphids twice (three and two years ago) for my hops. I had a pretty bad aphid problem three years ago. Last year, they just showed up again, so I figured that they hibernated nearby and came back. They have a lifespan of 1-2 years, so I'm curious if I'll need to introduce more at any point. I've noticed that there are zero aphids thus far, but I also noticed about two ladybugs tonight. It's somewhat early in the season, but I'm curious if others have gone this same route. Since the hops attract aphids every year, do the ladybugs stick around so that I won't need to go an introduce more, or will I need to get some more every three to four years?

Sevin dust works but honestly its pretty terrible for beneficial insects as well. It will kill pretty much anything on contact including ladybugs which in healthy numbers will keep your aphids at bay.

For caterpillars I use a product that contains Bacillius thuringiensis which will naturally kill most larvae that decide to eat the leaves and as an added bonus is *mostly* healthy for all other beneficials.

As far as lady bugs go I have released a few thousand over the last couple of years and have seen them everywhere this year. In theory they should be reproducing. I have not seen many aphids at all and the ones I did, the ladybugs were on them and quite happily munching away!

So my mother suggests just some dish soap diluted with water in a spray bottle. She says she uses it on all of her vegetables. Although my bines haven't flowered yet, I'm not comfortable using soap because of the threat of a lingering taste or smell. I thought about just spraying my bines with star san. Anyone else try this?
