Yes, row covers work well against aphids, also against flea beetles and root maggots. I use the very light grade (Agribon-15). Install it early in the season before the insects come out. Secure it tightly to the ground and ensure there are no gaps. Unfortunately, it has a tendency to rip more easily than heavier grades.

Just be aware that IF an aphid manages to sneak in underneath, you will have an aphid population explosion underneath the covers.

Sounds perfect, thanks!

"Just be aware that IF an aphid manages to sneak in underneath, you will have an aphid population explosion underneath the covers."

That, unfortunately, has been a frequent occurrence for me when using Agribon 15. I use it as a cover for isolation cages, (when growing peppers for seed) and have had some serious infestations. Haven't figured out yet whether the aphids get on the plants during hardening off (in a small greenhouse) or whether they can find holes in the very loose weave of the AG 15.

Fortunately for me, I have a very robust population of predatory insects... the Agribon actually protects the aphids from them. All I have to do is leave the cover open, and within a week or two, lady bugs, syrphid fly larvae, and yellow jackets will eliminate the aphids.

Hey there zeedman,
Haven't received anything yet; I suspect Customs is messing around with the seeds :)
