well my agave did have grubs

calb_gardnerOctober 25, 2009

well my big agave is gone ...surprisingly not the one that I thought was sick. but one of my biggest.

so today was spent pulling it out and digging up all the dirt and grubs.

Man there were tons of them.

I treated the area and all the rest(I have 30 plants ) with Bayer systemic tree and shrub protect and feed. it has 1.47% imidacloprid

I mixed 6oz in 3gal of water. I hope that was right I had to wing it on the measuring. the directions say treat again in 12 mts but I think I should do it sooner

Any suggestions???

I will try to post some snaps in another thread.

Imidacloprid is the stuff to use. My experience seems to indicate that once every 12 mos. is better in climates with shorter growing seasons, but I'm waiting for official research to confirm or deny that. In the absence of firm evidence, it's smart to take the bottle instructions as truth,

One thing you can do to prevent the grubs from coming back is to sprinkle permethrin granules around the base of the plants in March and April to kill the adult beetles before they lay eggs.

Good luck! : )

Sorry to hear it really WAS agaves--not fun at all. I've only used the ready-to-spray Imidacloprid stuff so I can't help you on any of their other formulations, but it's great stuff to use for sure. The ready to use spray suggests reapplying after 30 days I think. In any case, good luck and do keep us posted.

Thanks for emailing me your pics. Below are two of them embedded (I hope) and in the link section is a link to a small public photo album I made that has all of the six or so pics you emailed me just in case some folks can't see the embedded pics.

Calb_gardner's agaves' weevils.

Sorry again and super good luck. My agaves and I live in constant fear about these weevils, LOL.

Take care,
Grant
