Silwet* L Ag (trisiloxanes) molecular characteristics provide an important advantage when compared with conventional adjuvants.
Tensioactives molecular structure has two parts, one hydrophobic and the other hydrophilic. Silwet* L Ag molecule has a very compact hydrophobic part that makes spraying broth offer no resistance to its target (weed, insect, crop) and, as a consequence, it facilitates spread; on the contrary, conventional adjuvants have a longer hydrophobic part offering wider contact with the target, making spread more difficult.
Resistance to rain will depend on Silwet* L Ag concentration and the spraying broth volume. The higher the Silwet* L Ag concentration, the more the penetration capacity provided if volumes are under 100 liters/ha. At a rate of 10 ml/100 Silwet* L Ag per liters of water neither stomatal penetration nor rain resistance will be obtained. A minimum of 20 ml/100 liters of water (that can rain after an application) will be necessary to start having resistance to rain (stomatal penetration) that occasionally may fall after an application.
• Coverage improvement.
• Broth volume reduction.
• Applications efficiency improvements to reach difficult places such as the back of leaves.
• Reduction of free time of rain after applications.
• Surface tension and spreading capacity.
Directions for use
Terrestrial applications rates range from 25 to 50 ml/100 liters of water (the higher the rate, the stronger the resistance to rain). Silwet* L Ag can also be used at lower rates (between 10 and 20 ml) and in this case, without resistance to run off by rain but an excellent behavior as an ordinary tensioactive. It will only reduce surface tension to allow agrochemicals to go through the cellular wall and no by stomata. Aerial application rates go from 50 to 100 ml/100 liters of water. Silwet* L Ag must be the last component added to the broth. For safety reasons, shakers should be turned off, to avoid possible agrochemical splashes.
What can Silwet* L Ag be used with?
Fungicides: Silwet* L Ag is special for foliar fungicide applications since it provides excellent crop coverage and, it is resistant to rain run off due to its quick stomatal penetration.
Herbicides: Silwet* L Ag is special for post emergence herbicide applications to control difficult weeds; it also behaves well with the use of pre emergence herbicides as it helps them to distribute uniformly on soil.
