RM43 43% Glyphosate Plus Weed Preventer Total Vegetation Control kills grasses and weeds and prevents re-growth for what does jiraiya’s headband say up to 1-year. Do not apply over the root zone of desirable plants. Receive an email if this item is back in stock.
Use extreme caution around pets and people. This is a hazardous product that can cause a host of health problems. A common complaint was that this product arrived with the contents spilled out. Apparently, the problem is in the cap and foil area that is not sealed properly. It is shipped in a plastic bag and then also boxed.
Glyphosate is often tank-mixed with auxinic herbicide 2,4-D for grass and broadleaf weed control. Here we examined the possible interaction of 2,4-D and glyphosate in barnyard grass, Echinochloa colona (L.) Link. The results showed that 2,4-D antagonizes glyphosate remarkably in glyphosate-resistant populations but only marginally in susceptible populations. This antagonism is related to reduced glyphosate uptake and translocation.
Less water equals fewer calcium and magnesium ions to tie up the glyphosate. RM43 contains Imazapyr, which Roundup does not. This ingredient kills any new plants in the area of treatment for up to 12 months. Wait 14 days after application before reapplying, to give both products time to work.
That is why it “kills weeds, roots and all.” It breaks down quickly in the soil. However, when accidentally over-sprayed onto the thin or pigmented bark of young trees, glyphosate accumulates in the phloem and can take years to break down. To kill small trees and other brush, spray at the highest recommended concentration as indicated by the label. This concentration will vary by species, but is generally 1 to 2 percent when using a hand-held sprayer.
As expected, glyphosate-susceptible and -resistant plants were unaffected by 2,4-D. However, for the glyphosate-resistant plants, 2,4-D remarkably antagonized glyphosate efficacy in both the target and nontarget site-based glyphosate-resistant populations (Table 1; Fig. 1). Similarly, this antagonistic effect of 2,4-D on glyphosate was evident for the nontarget site-based glyphosate-resistant plants (Table 1; Fig. 1). These nontarget site-resistant plants were controlled at the higher glyphosate rate of 1620 g ha−1.
This indicates that the 2,4-D antagonism is dependent on the plant’s intrinsic sensitivity to glyphosate. As there are now many glyphosate-resistant barnyard grass populations,23) as well as glyphosate-resistant grass weed species,28) care should be taken with 2,4-D/glyphosate mixtures. Trays were placed in a greenhouse with average day/night temperatures of 33/25°C. No precipitation or formation of foam or gel was observed in the mixture during preparation or afterward. Each treatment had three replicate trays, and each tray contained 30–50 plants. The herbicides were applied using a cabinet sprayer with a spray volume of 118 L ha−1 at a pressure of 200 kPa and a speed of 1 m s−1.
