questions about glyphosate planting comming soon

hey guys and gals any info on this apprec. how long do you wait after spraying to plant what is the best price and location for buying this what quantities does it come in and what is the water to Ghyph rate to mix this thanks hey john how are you doing havn"t heard from you in a while you too vitalis

The only reason you"d spray RoundUp before planting would be to kill existing growth. Normally, tillage is used to kill existing small growth of weeds before planting. RU is a contact herbicide with no residual action. That means it kills only weeds that are emerged and growing, and there is no effect on weeds that emerge later. You don"t mix any herbicide and water in a certain ratio....you first calibrate your sprayer to determine how many gallons of water per acre it puts out, then you add herbicide at the recommended rate per acre. If you have no experience with this type of equipment or product, you need to take some classes on proper usage and handling, or hire the job done. Herbicides are not something that untrained people should mess with.

Are you planting Round-up corn, beans or Alfalfa. They can take it sprayed directly on them. glyphosate (round-up) has gotten cheaper than you can disk. $10 a gallon, If the rate is one quart,the cost is $2.50 a acre. Round-up needs no sticker or adjunte mixed with it. 10 gal per acre is enough water. 20 to 30 psi. is about right. We spray as soon as can get in field. then after we plant, then after we put on Nitrogen (corn) with a little resuidual herbicide. beans about 8 inches tall.

Remember, read the label and follow it, it's the law. don't 'just' go by what you read here.

There are at least 2 common types of glyposate, 4 lb and 6 lb. One is stronger than the other, so know what you are buying and follow the label... (I believe I've head of a 5lb as well???)

For 4 lb, you plant roudup ready crops, wait for the weeds to grow, and spray them. Glyphosate only kills greemn plants that it gets sprayed onto the green parts in good weather. It has _no_ effect on seeds in the ground, etc. The very next day new weeds will be sprouting and start to grow.

Typically glysophate prefers less water per acre than other types of spray, you would mix up about 10 gallons of water and around 32 oz of glyphosate to spray per acre. See what your sprayer puts out, and adjust so you get about that much glyphosate per acre. Sometimes for tough weeds you would want more; sometimes with tank mixes or for other reasons you might want only 1/2 that much.

It is very very very common to add a few lbs of a special nitrogen fertilizer (typically granular, tho a lot of liquid type has been developed now too) which basically softens hard water - glyphosate tends to bind up with hard water and will not be so effective without this.

It is possible to buy glyphosate with or without additives that help it stick to plants and break in through the waxy leaves. Depending on what your label says for the product you buy, you may need or want to add some of his.

That is the very basics. There are a zillion different 'brands' of the stuff, and so hard to say what you should or will buy. For farm use it typically comes in 2.5 gallon jugs, 30 gallon barrels, 250 gallon totes, or you can buy in bulk and need to bring your own approved container to pick it up in. Most of us have good results with generic, imported, or brand name stuff, all seems to work the same anyhow for most of us - the only difference is the strength (lbs of active ingredient) and additives (the sticky/ wax cutting stuff) included in what you buy.

Do look at the label and dirctions of your product for exact requirements and mixes for the crop and weeds and weed size you are dealing with.

Will you be planning on spraying anything else before or with the glyphosate? Will you plan on doing 2 sprays of glyphosate? Especially in the south, but up here in the north too, a few species of weeds have developd resistance to glyphosate and you might need stronger mix to deal with them, or better idea use a scond, different herbicide to deal with them. Any of this can change the amount you ned to use. It is rare for just one spray of glyphosate to take care of the weeds for the whole year; spray early & you will get a second flush of weeds. Spray late and the weeds are large & hurting your crop already....

You can't learn all you need to know about dpraying weeds from a quick question on a discussion board. You need to do some serious reading on the subject. Start googling and reading .edu sites, the AG Colleges. Go to your local ASCS office ( Do you know waht and where that is?) They have a ton of free books and literature on spraying and weeds.

In addition to the excellent advice below: 1. Make sure the plants you're trying to kill are growing. Warmer temps are better than colder. 2. Better if the weeds are dry than wet when applying. Problem will be waiting until later for dew to dry off may result in winds, which is not good. 3. If what you are trying to kill before planting is broadleaf, it might be cheaper to use something like 2-4D. 4. If what you're trying to kill puts out rhizomes, i.e. quack grass, make sure the plants are fully infected before introducing ant tillage including the planter or drill opening coulters. 5. I like to add 17# of ammonium sulfate per 100 gallons of water to the sprayer tank PRIOR to adding the glyphosate. It makes the mix stickier.

I also would like to use this on potatoes and veggy's any other tips boy this is a good site thanks alot guys been a while since I did any of this and needed a reminder blw

The only crops, so far, that are "Roundup Ready" are limited to corn, alfalfa, soybeans,cotton, canola and sugarbeets. No other crop(so far) has the genetic modification to make it totally immune to the herbicide glyphosate. So, if you're planting other vegetable crops, use the roundup before planting and after harvesting if you desire but don't even think about using it on a non-roundup ready crop as it is a powerful plant killer. I believe it is used on pototoes just before harvest to kill the vines.
