Can I start applying fungicide to my tomatoes as I am planting them in the ground or is this to early? Also does applying this to the tomatoes when they are blossoming hurt pollution
You can start early if you would like. Fungicide is preventative so it needs to be on the leaf when the spores are floating around in the air. Fungicide does not hurt pollination. Tomatoes are self pollinating so the pollen just has to fall from one part of the flower to another. I would guess if you jetted the fungicide in to the flower on purpose it would blow all the pollen out of the flower, but the normal gentle spray won't affect it. When you plant your tomatoes immediately mulch around them. The mulch will keep spores in the ground from splashing up on the plant when it rains or you water.
Those are the same kind of fungicides that are used on cucumber leaves. Here are two extension publications that might help on this: This Publication is for home gardeners. Part way down it lists problems these links have some good information on downy and powdery mildew: extension.umd.edu/hgic/topics/cucumbers This publication is for the commercial grower. it lists some restricted use pesticides that the home owner cant get. It does have useful information. It also talks about Mancozeb and Chlorothalonil that the homeowner can purchase: content.ces.ncsu.edu/cucurbit-downy-mildew

Can these fungicides be used on cucumber leaves too??
