Rated 1 out of 5 by from Waste of money Used this several time for the duck weed in my pond, has done nothing. Followed instructions and used a surfactant. Tractor supply won't give a refund because it's a "hazardous" chemical.

Rated 5 out of 5 by from Excellent Results when properly applied My first application failed due to not following instructions! After adding surfacant (keeps the weedtrine on the surface) it has worked well in several other ponds for duck and meal weed removal. Highly recommend the product. I used a motor driven pump to create a fine spray on to the ponds.

Rated 5 out of 5 by from Goodbye Duckweed We bought some property with a 1/2 acre pond full of duckweed on it, took a couple of applications, but killed all of it. Very satisfied with product.

Rated 1 out of 5 by from Not for Baby Pondweed I wasted $80.00 on a gallon of this product. I applied it to a small area in my pond to see how it worked. It has not killed the Baby Pondweed that is in my one area pond. In fact I can't tell any difference in the area treated from the area untreated. I can not recommend this product.

Rated 1 out of 5 by from not very effective Wild ducks left me with a pond full of duck weed.I have used this product twice this year and I still have a pond full of duck weed.It would kill off maybe 1/4 in week to 10 days and this stuff replace's its self in 2 to three weeks, so lots of money for nothing.Don't know what to use any more.

Rated 5 out of 5 by from Great Product I own several ponds which all have weed problems here in S. Al. I purchased many chemicals liquid and granular all of which failed miserably but after buying and using weedtrine D my attitude changed about winning this war on pond weeds.It worked very well total eradication of all weeds in my lakes. It took several weeks but whacked them all.

Rated 5 out of 5 by from Great Product We have purchased this product over the laste several years. It was bought for floating weeds in the pond and after one treatment the problem is gone. Its good to know that TSC carriers products that work!

Weedtrine-D would eventually kill cattails. In most cases the damage to fish and wildlife is minimal if any when used properly.
