Hello,
Has anyone found a cheap way to prevent mosaic virus without using expensive physical barriers? I’ve been using sticky traps and spraying every few days, the patch is kept clean, and I always wash my hands after weeding before touching the plants (I know it can only take one bite from an aphid and it’s over). I also disinfected all my 2025 tools with a 10% bleach solution, so I suspect aphids are still the main issue. Any tips for getting better control of them would be greatly appreciated!

Eliminate alternate hosts. (The following is cut and pasted from A.I.)
Squash Mosaic Virus (SqMV) has a narrow host range mostly limited to the gourd family (Cucurbitaceae) like squash, melons, and cucumbers, plus a few alternate weed hosts in the goosefoot family (Chenopodiaceae).Primary and Alternate HostsCucurbit Crops: Melons (principal host), summer and winter squash, pumpkins, cucumbers, and watermelons.Weed Hosts: Certain broadleaf weeds, particularly members of the Chenopodiaceae family, such as common lambsquarters (Chenopodium album), Russian thistle, kochia, and maple-leaf goosefoot. Other non-cucurbit crops like peas and wild-growing chervil have also been noted as occasional hosts.

I do not have any cucumber beetles anywhere so i thinl its either zuchini or cucumber mosaic virus but i do not know which type is transmitted by which pest only by my research ive seen that squash is caused by cucumber beetles

You might be able to prevent aphids by increasing the brix of the plant, and lowering nitrate and chloride. If you've used potassium chloride switch to potassium sulfate. Make sure your iron and manganese are maxed. Also copper & molybdenum are cofactors for utilizing nitrate...? In other words if you add the right micronutrients then any excess nitrate in the plant should get utilized by the plant rather than attracting aphids. I'm not sure why this is the case that aphids choose to attack plants that are high in those nutrients. Presumably they have taste buds (or whatever they have) and that's what tastes good to them. I'm repeating the advice of John Kempf (advancing eco agriculture on youtube) because he seems to have observed and studied this, he seems to have firsthand knowledge about it.

you seem more sanitary than most so you are certainly not the cause. Pests probably. Load your plants with lady bugs. The gals will eat all the buggies spreading disease. You can actually buy a bunch if you didn't already know. However, they won't touch the beetles, but aphids, mites, yes. I've used DE on my potato plants and this precluded beetle destruction. Just a thought
