1. In a field experiment, the effects of MH (maleic hydrazide) treatment by seasons on growth retardation and appearance of several turfgrass species were studied.2. Manilagrass maintained normal leaf colors but showed little retarding effects.3. A significant suppression on growth of Japanese lawngrass was observed when it was treated in May at a rate of 0.5cc (product) /m2 but a reddish discoloration of the tips of leaves was found at higher temperature.4. For Bermudagrass, the treatments during May to June were effective.5. Effects of autumn treatment on cool season turfgrass lasted till next spring which might suggest a better result with an early spring treatment.6. The retarding effects decreased remarkably by rain or irrigation shortly after MH application.
