If you hit a thistle in bloom with a wiper you are going to create a thistle theme park. Each head can drop over 10,000 seeds.

I need to turn my neighbor in, he is upwind from our property and each year, he has large patches of Canadian thistle bloom and spread over our property. I mow and spot spray.

NOT applying herbicide and permitting thistle seed to blow in the wind would be better?

At any rate, wipe the thistles two times, or as necessary, before they seed.

Roundup, maybe maybe not, 2,4-D is a better choice IF you use crop oil or a "sticker" with it. Crossbow is even better but still use a "sticker" like "Preference", "Cimarron" is your best choice. It's very expensive but you use very little. This coming from practicial experience of using the previous products.

Mow the thistles before they go to seed. For now they are just doing the job they were created for; covering barren soil, protecting it from the hot sun, and erosive rain, and wind. The condition is one of a temporary nature, and the thistles will go away in large part once the grasses take over. Weeds are the Guardians of the Soil.

Publisher's Preface

SO FAR as we are able to determine this is the first book to be written in praise of weeds. Many are the books which treat weeds as pests, and each season sees an advance in anti-weed campaigns and techniques; a host of chemicals, mechanical eradicators and even flame throwers are making life increasingly hard for nature's greatest and most widely dispersed group of plants -- the plants which stand condemned because they are deemed "out-of-place."

That the ordinary garden and roadside weed might have a vital function in the scheme of things and be of inestimable value to mankind seems not to have occurred to most agriculturists, whether in the classroom, the departments of agriculture or on the farm.

The author of this book has been teaching conservation and biology for close to fifty years. But he has been a student as well and a keen field man who has specialized in the ways of weeds, not only in his home state of Oklahoma where he has spent much time learning from the Indians, but in other parts of the world -- in Europe, India and the Philippines, particularly.

According to Joseph Cocannouer, weeds -- the common ragweeds, pigweeds, pusleys and nettles, to mention four -- perform the following valuable services among others:

1. They bring minerals, especially those which have been depleted, up from the subsoil to the topsoil and make them available to crops. This is particularly important with regard to trace elements.

2.When used in crop rotation they break up hardpans and allow subsequent crop roots to feed deeply.

3. They fiberize and condition the soil and provide a good environment for the minute but important animal and plant .life that make any soil productive.

4. They are good indicators of soil condition, both as to variety of weed present and to condition of the individual plant. Certain weeds appear when certain deficiencies occur.

5. Weeds are deep divers and feeders and through soil capillarity they enable the less hardy, surface feeding crops to withstand drought better than the crop alone could.

6. As companion crops they enable our domesticated plants to get their roots to otherwise unavailable food.

7. Weeds store up minerals and nutrients that would be washed, blown or leached away from bare ground and keep them readily available.

8. Weeds make good eating -- for man as well as for livestock. The publisher can vouch for the superiority of lamb's quarter -- a favorite of the author -- over any other domestic form of spinach or cooked greens.

No, Professor Cocannouer does not believe that weeds should be allowed to go rampant and take over our farms and gardens. The function of this book, a pioneering work, is to demonstrate how the controlled use of weeds can be sound ccology, good conservation and a boon to the average farmer or gardener.

Thistle is illegal in Iowa. We had several acres infested with it. Since it didn't bother us we didn't pay much attention to it. Well until "weed police" showed up and educated us about legality of having them. He said it will take about three years of work to get them under control. We used pull and burn them method. They are easy to pull after rain when the soil is soft. I think if all put together the pile would be double garage size the first season. Once the ground cover such as grass takes over the thistle more or less disappears. We still have some that I pull and burn. Mowing work only till early summer. Once they bloom and start developing seed mowing them makes the matter worse.

"The condition is one of a temporary nature, and the thistles will go away in large part once the grasses take over."

Good luck with that plan - LOL.

Weed Wiper dispensing Roundup/Glycophosphate or a specialty version of same, might be a good bet. No wind drift of herbicide with a Weed Wiper properly used.

Garden Center Roundup is about 18% Glycophosphate.

Tractor Supply Company sells house brand 41% Glycophosphate relatively cheaply.

There is a pre-made one of those for about $110. Also Smucker makes one
