บทคัดย่อ (EN): Pest and disease incidence existed in rubber plantations from the beginning of its commercial cultivation. Timely management of these biotic stresses that can either retardation of growth or reduction in yield is an important step towards the sustainable production and productivity of natural rubber. Development and introduction of various equipments and devices for the application of chemicals to control pests and diseases in rubber plantation also have a history that is as old on the history of rubber cultivation itself. Both high volume and low volume spraying devices are being used either for prophylactic or curative application of pesticides in rubber plantations. Significant developments in terms of improvements and modification have taken place in the spraying technology in rubber cultivation. The spraying devices used, their performance, upgradation, modifications etc. from the beginning of commercial cultivation of natural rubber in India from 1902 are discussed here. Napsack and backpack sprayers are used for nursery and immature plants to manage various disease. These sprayer working under hydraulic pressure have been modified to electrically operated back pack sprayer, due to which manual labour could be reduced considerably. Rocker sprayers which were manually operated are also modified to electrically or mechanically driven systems, which have considerably reduced the labour. The use of low volume sprayers especially mistblowers in rubber plantations commenced for managing abnormal leaf fall disease caused Phytophthora spp. during 1957 to 1960. During this period micron 420 with BSA engine was used. This machine having a weight of 120 kg. required 8 workers for operation. But later through various modifications of engine and blowers the efficiency was improved considerably, reducing the man power requirement as well. Due to the paucity of helicopters for aerial spraying, tractor mounted mistblowers were also developed in due course which could deliver the spray fluid to above 90 feet. Considerable man power saving could be achieved by this technology also. Development of Mistblowers-cum-duster operated by one person is another significant achievement in the plant health management recently. Progressive developments and changes taken place in the spraying technology in rubber cultivation during the last few decades are discussed in this article.
