Dragon Fruit is one of the important crop plants in South Borneo. Efforts to increase production are sometimes inhibited by pathogenic nematodes. The aim of this study is to identify and describe the nematodes found in the soil around the dragon fruit farmland in Banjar and Banjarbaru districts. Research was done by taking the soil at a depth of 0-20 cm near the roots of the dragon fruit. The nematode extraction was done with Whitehead & Heaming method (1965) and fixed by Seinhorst method (1962), then proceed with mounting method Seinhorst (1959). Furthermore, morphological observations consisted of the entire body from head to tail. Nematodes that have been identified on the Dragon Fruit farmland are the genera Pratylenchus, Rotylenchus, Tylenchorhynchus, Mylonchulus, Eudorylaimus and Nygolaimoides. The identified nematodes may serve as additional information about the nematodes present in the dragon fruit farmland.

Combinations of antagonistic herbicides can be helpful in the search for seed-applied chemical safeners to protect crop plants from herbicide injury. If a particular herbicide combination is selectively antagonistic so that the crop is not injured but weed control efficacy is not reduced, it should be possible to develop a new, more selective formulation of the herbicide which includes the antagonist or antidote. A promising new approach involves the use of early pretreatments of crop plants with subtoxic levels of a particular herbicide to increase crop tolerance to later, higher rates of that herbicide. When there are different mechanisms for herbicide detoxification in different plant species, it should also be possible to develop selective herbicide synergists that would provide equal efficacy at lower rates with greater crop tolerance. As our knowledge of herbicide metabolism and mode of action develops, it will be increasingly possible to use other chemicals to selectively synergize or safen herbicides to solve problems in important crop-weed situations.
