Sulphur Boost


Why Is Sulphur So Important To Plants?

Sulphur is an important nutrient and provides plants with the necessary amino acids, vitamins, proteins, antioxidants, and enzymes. It is a key element in healthy plant growth, and will improve biological activity which bolsters the immune system of plants; improving their resistance to a variety of diseases.

Sulphur deficiency in plants can also result in yield loss and reduced fruiting, which can be countered with the application of our Sulphur Boost.

Sulphur Boost is a 100% natural, micronised liquid fertiliser, which increases the amount of sulphur plants absorb.

Use Sulphur Boost In Combination With Our Natural Predators

Conventional formulations of sulphur can be harmful to beneficial insects and the natural enemies of insect pests. This is not the case with Sulphur Boost, which can be used safely in combination with beneficial insects and will leave no harmful residue. Sulphur Boost has no negative effects on plants, or the environment, and is safe to wildlife and humans. Sulphur Boost is a 100% natural liquid nutrient.

Sulphur Boost Benefits A Wide Variety Of Plants 

Sulphur Boost can be used on many different plants including cucumbers, which conventional sulphur formulations cannot treat. Roses benefit especially from the application of Sulphur, as it protects them from powdery mildew and black spot. Other plants that benefit from sulphur applications include tomatoes, lettuce, vines, strawberries, grass and many ornamental plants.

Sulphur Boost leaves less residue on leaves than conventional formulations, but still may leave some.

Where Should I Use Sulphur Boost?

Sulphur Boost can be applied outdoors and in greenhouses. Please avoid spraying the boost in greenhouses when there are high temperatures, however. 

How Do I Apply Sulphur Boost?

Sulphur Boost is supplied as liquid concentrate in an easy to use dosing bottle. The dosing bottle helps measure the correct amount of concentrate to dilute with water.

Shake bottle thoroughly before mixing up the solution. Dilute 10-30ml of concentrate 10 litres of water to form the solution. Apply the Sulphur Boost at a pH of 5-7.

Apply the solution with a sprayer, hand sprayer, or Knapsack sprayer. For best results when spraying, ensure to utilise a fine nozzle.

The solution can be applied as a foliar application to leaves. Apply over the entire plant canopy and to as many leaves as possible, focusing on the upper parts of the plant.

If you have added adjuvant, this should be mixed with the Sulphur Boost at a dilution rate of 15-20ml per 10 litres of water.

Can I Apply Natural Predators After Using Sulphur Boost?

If applying Sulphur Boost before the use of natural predators, please wait at least 2 weeks before applying the beneficial insects.

If you are wishing to use Sulphur Boost after having applied predators please wait at least 4 weeks before applying the boost.

How Much Sulphur Boost Do I Need?

We offer two unit sizes, at either 500ml or 1 litre.

The recommended unit size for professional growers is 5 litres. Contact Dragonfli for more information regarding application on professional sites.

How Often Should I Apply Sulphur Boost?

Do not exceed the maximum dose or apply in extremely hot conditions (especially under glass) as this may scorch sulphur susceptible plants.

Do not use on plants more than 7 times a year.

Good for black spot on roses

Tried this for climbing roses which had extensive black spot last year and Roseclear etc made no difference. It would seem the last 4 weeks, since application, has seen a marked reduction in new leaves being affected. I had hoped it might help with apple blossom wilt but sadly no difference.
