It occurred that tropical fruit trees in grassland were eaten by grazing cattle, and they will be ceasing to grow soon. In this study we tried to protect the tropical fruit trees from grazing cattle by means of odoriferous materials in grassland. Papaya (Carica papaya L.) which cultivated in pods until 40 to 50cm height in green house transplanted in grassland. Three experiments were conducted. Following experiments on protecting tropical fruit tree from grazing cattle were made : 1. Effects of five kinds of odoriferous materials (butyric acid, ammonia, trimethylamine, propionic acid, butylmercaptan) which put in processed polyethylene resin bottles with absorbent cotton on protecting fruit tree from grazing cattle; 2. Effects of three setting methods (that is, there are method of heap cloth mat soaked butyric acid under the fruit tree, of polyethylene resin bottle, and of heap cloth mat added polyethylene resin bottle) of using butyric acid which was most effective in experiment one on protection fruit tree from grazing cattle; 3. Effects of three concentration levels of diluted 50,100 and 200 times butyric acid solution on protecting fruit tree from grazing cattle. The results obtained were as follows. The most effective odor material which protected tropical fruit tree from grazing cattle was butyric acid, and were higher effect in order of butylmercaptan, trimethylamine, ammonia, propionic acid and no-odor material.
