Rice is the major crop of most farmers in Indonesia. One of the limiting
factors in rice cultivation is brown planthoppers (Nilaparvata lugens Stal.).
Various methods to control, such as cropping technic, biological control,
insecticides including integrated pest management have not been able to
overcome this problem. Therefore it need an alternative methods of control which
safe environmentally and be able to control brown planthopper populations
effectively. One of them is by using zeolite. Zeolite is pest populations control by
increase plant resistance. This research was supposed to study the potential of
zeolites to control brown planthopper population.
This research was carried out on May until November 2012 in the rice
fields in Joho, Mojolaban, Sukoharjo. This research was held in Split Plot Design,
zeolite and IPM as main plot and varieties as subplot. There are eight
combinations of treatments which have nine repeated. Data were analyzed by F
test and DMRT at 5% level.
The results showed that zeolite treatment had correlation with adult brown
planthopper populations, but had no effect on the nymph of brown planthopper.
There was a correlation between varieties and control methods. But it was likely
occured at 6 weeks after replanting observation. At 6 weeks after replanting
observation, application of integrated pest management (IPM) indicate a higher
population than zeolite. At 6 weeks after replanting observation, the zeolite were
not able to reduce the level of damage to the rice crop. Addition of zeolite in rice
farming had correlation with plant height and number of tillers of rice. The
addition of zeolites can be used as an alternative to control brown planthopper
population and to increase the growth of rice plant
