How to Apply ▾
- Apply evenly using a broadcast spreader.
- Typical rate: 5–7.5 lbs per 2,000 sq ft.
- Rates vary from 100–200 lbs per acre depending on target weed.

Initial results appear within 7–10 days. Full control typically occurs within 3–5 weeks as weeds die and decompose.
For heavy infestations, apply in lanes with untreated buffer strips (50–100 ft wide) to prevent oxygen depletion. Treat buffer areas after initial treated zones have decomposed.

Best results occur when applied in spring and early summer while weeds are actively growing.
Late season applications are possible but may require repeat treatments and results may not be fully visible until the following season.
Water pH below 8 generally yields best performance.
Active Ingredient ▾
27.6% 2,4-D (Butoxyethyl Ester of 2,4-Dichlorophenoxyacetic Acid)

Pretty good
Size: 1 Pound
So we're on the outside, not terribly sweet on the inside. Not the most sour candy I've ever had but very good and I really love sour things. It's fun watching people who don't like sour things eat them.

Love it
Format: Hardcover
Love. Love. Love.
I love this book.
Every single word in this book is so precious to me.
If Gesenius was like a strict father, this one is like a mother who so kindly elaborates on many difficult notions.
Thanks a lot for such a great book ❤️
(Even if it were $1000, I would buy it! The bibliography is so kindly sorted out by a subcategory~♡)

An indispensible Hebrew Language resource.
Format: Hardcover
This book is an amazing resource for anyone who has completed preliminary Hebrew such as with Pratico and Van Pelt in their Basics of Biblical Hebrew. This book goes above and beyond, it gives the diagnostic origin patterns for adjectives, patterns in noun formation as well as other components of speech, contrasts each of the seven major verb forms and the minor forms as well, and gives an excellent evolution of the utilization of the Hebrew language and its update in characters.
It explains in its initial history a lot of unique statements in the Torah, and illustrations throughout give the reader an excellent idea about the Hebrew Scriptures. I bought this to aid in designing a language studies course at seminary and it has stood me in great help so far, going beyond anything I would have expected to get out of an intermediate level grammar and is an amazing, invaluable, and priceless resource, both to the professor, and the student. I recommend all people taking Hebrew purchase this book and add it to their collection and read it through cover to cover as well as using it as a topical reference guide.

can potentially be overwhelming
Format: Hardcover
This is a good resource for introduction to syntax. However, the vast amount of examples has benefits as well as disadvantages. The benefit is that it is comprehensive in information which makes it good for a reference. The disadvantage is that the many subcategories can cause one to be discouraged as the quantity of information may be overwhelming. Nonetheless that is the nature of learning a language.
It is still a good resource if you can maintain the brain power to understand the technical language if you have a novice background to linguistics. The volume could be more pedagogical however that would cater to the self learner and perhaps that was not the intent of the author. This volume seems to be designed for the classroom setting. However it is still decent for the self learner.

Favorite Hebrew Reference Book
Format: Hardcover
This is the Hebrew grammar that I use the most often. While I also use Williams and Arnold and Choi, this grammar is more comprehensive, and its size certainly reflects this. It probably betrays my inclination towards the exactness of Greek to like this grammar so much. As my Hebrew professor often tells us, all these grammar categories are contrived to some extent, so at some point it isn't helpful anymore to go further in depth on the uses of the so-called "cases."
All in all, I usually find it easy to locate the grammatical point in which I am interested, though sometimes I have to resort to looking up every instance a Hebrew particle occurs throughout the book. For this looking up of various nuances of a particle, I sometimes find Williams more user friendly. Nevertheless, Waltke and O'Connor's volume has been my resource of choice.
