Therefore, it can be concluded that microbialenriched CT can be applied as a curative treatment in inhibiting the development of powdery mildew on melon plants, hence reducing the dependency on chemical fertilisers. The powdery mildew colonization on melon leaf surface was suppressed apparently due to inhibition of conidial germination. Hence, it limits the number of penetration pegs produced, which in turn may prevent the spread of disease. However, the CT associated mechanism of suppression is difficult to determine because CT represents a microbial community rather than a single species.
