SW7 is a silicon based wetter designed to give enhanced coverage and consequent uptake of foliar nutrients.
The silicon-oxygen bonds are hydrophobic and the organic clusters are hydrophilic, creating a superior wetting agent, which spreads quickly to cover a large surface area—greater than conventional surfactants.
At higher application rates, microscopic examination reveals a high degree of stomatal flooding often occurs, which can extend into intercellular spaces. Therefore, SW7 can be particularly beneficial on crops where it is difficult to achieve good coverage.
Also at the higher rate, SW7 can supply silicon to the crop. Silicon is widely recognised as a beneficial element to many crops. It is transported in the xylem and deposited in the epidermal cell walls. It complexes with calcium to help strengthen cell walls and also helps to alleviate abiotic and biotic stress.
SW7 can be mixed with a wide range of foliar nutrients. Always consult the appropriate nutrient product guide before use. It is suitable for dilution with both hard and soft water.
Use 0.05 – 0.1% dilution with foliar nutrients in a minimum of 200 l/ha water.
The spray tank should be filled with half the required water. Add the required amount of SW7 to the water before adding any nutrients, maintain constant agitation. Add remaining water to correct dilution and spray.
Do not apply in tank mix with pesticides when crop is showing deficiency symptoms, is under stress, or in adverse weather conditions.
SW7 is particularly effective when used with Foliar Supreme, Gard S, K50, Quad 14, and Vitomex, or other foliar nutrients where good leaf coverage is required.

Turf and Amenity
SW7 is a silicon based wetter, designed to ensure enhanced uptake of foliar nutrients. It also supplies silicon to the turf, improving cell strength and resilience to attack by pests, such as frit fly. Silicon is widely recognised as a beneficial element for plant growth.
Following application, it is transported in the xylem and deposited in the epidermal cells in the turf leaves. Once in the cells, it complexes with calcium in the cell walls and acts as a physical strengthener and also helps alleviate abiotic and biotic stress.
SW7 is extremely plant safe, and higher rates of application can help improve water penetration and help manage localised dry patches and issues of water penetration caused by hydrophobic soil conditions.
