Foliar spraying schedule for disease conrol/prevention

[kygreg]

If you who have regular spraying schedule for disease prevention/control and spray every week or every two weeks plus after each rain, do you spray after a rain if more rain is coming in in 10-24 hours or just wait until its all over? Thanks.

you talkin chemical folier sprays or nutritional sprays? I won't use toxic elements on my food.

The basic principal is; the healthier the plant is the less subject to insects and disease it will be, and getting more minerals into the plant in the right balance makes them healthy.

Kind of like us, the healthier we are the less disease we will get, higher immune system.

I am using "amaze" folier made by International ag labs, a specially formulated NPK + calcium combination, so it's completely plant usable. and I add liquid kelp extract to it, about equal amounts. (3/4 cup ea of the concentrate in 2 gal water, equal to the 2 qt in 20 gallons recommended) we shall see how well it works to defeat disease. (I'm not doing a real test, so it may reveal nothing, I'm just spraying everything) If rain washes it off it'll just feed the roots, but I do avoid spraying it in the rain or just before. Very early morning is the best time when the stomata are open.
It's something that I guess the more often it's done the better, with big farms it costs a certain amount for every application, and that has to be limited, they recommend 2 week timing, but I can do it every morning if I were ambitious enough. (which I'm not) 2-3 times a week is all I'm getting in.

With apple trees they say it puts a layer of calcium under the skin of the apple every time they're sprayed, (the leaf takes in the minerals and puts it in the fruit) I can hardly imagine the nutrition of an apple if it were sprayed every day, and I'm sure the flavor would be superb.

The immediate effectiveness of a nutritional folier can be judged by taking before and half hour after brix readings of the leaf sap. If the brix went up it was effective.

If you are using Daconil it is recommended weekly. I wait till after the rain.

Since you say for disease control/prevention I ask Freda to spray Daconil about every week if Late Blight has been spotted in the area b'c that's a serious one that can kill quickly. And since water falls out of the sky whenever it wants to and each season is different my approach is different every year.

This past Spring and even now it's been rain, rain, rain, but all I know that's out there right now is a bit of Early Blight, perhaps, so it usually makes sense, at least to me, to look at the weather forecast ahead and spray according to that forcast which at times has meant spraying more often than the weekly schedule.

Yesterday was sunny and beautiful and I was inside watching some tennis and all of a sudden I heard a HUGE clap of thunder which really surprised me b'c it was only an hour before that that I'd checked the radar and saw nothing.

Pop up T-storms are common and can't be predicted. They'll say 20, 30 % chance of T storms so who knows for sure.

If you are comfortable with it, fine, I'm not.

Normally once a week depending on the weather. If it's been sunny and dry maybe add a week. If we have had rain normally after the storm has passed unless more is coming. One reason I use Exel LG is because it is systemic and fights the disease from within as well as a contact. And yes it is a bio-friendly product. Ami

Yes, I'm very comfortable with it. I don't use it every year, only when needed.

Daconil has been and continues to be the most widely used anti-fungal in the world and there is more data about it than any other anti-fungal.

There are websites and folks that are Ok with it and after researching it from time to time since the late 80's I too am comfortalbe with it when needed.

There are those who grow organically all the time, those who never grow organically, and those who do a bit of both.

There are those products that are organic, such as Rotenone that have a higher toxicity than other products that are not organic, such as Chlorothalonil ( Daconil)

I don't care if a product is organic in the traditional sense, or not, what I care about is toxicity, to humans, pets, bees, the environment, etc.

There are websites that condemn anything not organically derived and those that take a more moderate view.

Each person has to do their own research and be comfortable with what they use in the garden and actually elsewhere.

That you aren't comfortable with Daconil, which can be used up the day of harvest which tells you quite a bit about toxicity, and I am, illustrates the different approaches that different folks can take.

I don't take issue with those who garden organically, for I myself do most of the time and I would hope that others wouldn't take issue with those who use non-organic products from time to time. All I expect is that someone researches what they want to use, maybe starting with EXTOXNET and moving on to the MATERIALS DATA sheets, in other words, using sources with non- biased data.
