Diafenthiuron acts by inhibiting mitochondrial respiration in susceptible insects and mites. This interferes with normal energy production required for movement, feeding and other essential biological functions.
Ramcides states that after uptake, pest mobility and reproduction cease and affected pests eventually become paralysed and die from starvation, generally over a period of several days.
Medusa is recommended for important sucking pests in crops such as cotton and okra. These pests remove plant sap and can reduce crop vigour when populations become high.
Timely foliar application with thorough and uniform coverage helps expose susceptible pests to Diafenthiuron and reduce continued crop damage.
Diafenthiuron provides acaricidal activity and is recommended against mites in crops such as chilli and citrus and against red spider mites in watermelon, okra and tomato.
Good spray coverage is particularly important because mites commonly feed on the undersides of leaves and other protected plant surfaces.
Ramcides Medusa is recommended against Diamond Back Moth in cabbage. Apply when pest infestation first appears and ensure uniform coverage of crop foliage.
Ramcides recommends applying Medusa at the appearance of pest infestation. Early treatment helps reduce pest feeding and population development before severe crop damage occurs.
Where another application is required due to continued infestation, Ramcides advises an interval of approximately 10–15 days, depending on pest pressure and the current label recommendation.
Ramcides states that Medusa is compatible with most commonly used products. However, compatibility may vary depending on the formulation and tank-mix partner.
