„Does ozone work on all plant diseases that affect coffee? That is what the research is working on. Coffee berry borer, coffee leaf rust, and coffee berry disease are the top three that are being worked on.“

Indian coffee board- monthly magazine- Cover Story- Importance of Shade for Co
„Shade limits the incidence of pest such as white stem borer and leaf rust disease in Arabica coffee. The incidence of white stem borer, which can cause death of plants, will be more in arabica coffee grown under less shaded condition (Subramaniyam 1941). During the current season, high incidence of white stem borer has been reported from most of the Arabica plantations on account of unprecedented low rainfall experienced for the past 2 to 3 seasons in South India. The non adoption of control measures for curtailing the incidence and also extraction of timber to tide over the situation caused by low price scenario for coffee aggravated the problem.“

„Large-scale field releases of this parasitoid have beeji taken up in the berry borer infested areas and in many cases it has been established and spread to nearby areas. The other parasitoid, Phymastihcus coffea is also under field evaluation now. The large-scale use of broca traps and the establishment of the parasitoid resulted in reduction of pesticide use considerably. At present, irrespective of size of holdings, spraying of endosulfan or chlorpyrifos is adopted only as spot applications.“

„Recently, however, many coffee farmers in northern Latin America have reduced or eliminated shade to grow new high-yielding coffee plants under direct sun. Fear of a disease known as coffee leaf rust sparked an early round of conversions, most of which took place in the 1970s. To prevent the spread of the disease, coffee farmers "technified," replacing older, shade-loving coffee varieties, such as t'pica and bourb--n, with new varieties, packed in tight hedgerows, that can survive open sun -- but only with chemical inputs.“

International Coffee Organization
„Current plans include the advancement of Arabica coffee in the western region by developing new cultivars that are resistant to coffee leaf rust disease, the replacement of many existing trees and a fuller distinction between grades. Uganda intends to compete vigorously in the gourmet market and has developed liquor profiles that will allow overseas buyers to select their preferred coffees. It is also intended to invest in washed processing facilities for presently dry processed Arabica and some Robusta.“

„Still need to test on effectiveness of ozone on coffee rust. Comments from the board members: Concern is that the bigger risk is from disease coming in through Central American pickers than green coffee and that issue hasn't been addressed. A motion was made stating that, "The Hawaii Coffee Association does not support house bill HB 477 - Banning the importation of green coffee into Hawaii, as we feel the current fumigation procedures are effective. We do not support any importation of green coffee currently outside the present department of agriculture rules; but we do support continuing research on alternative methods to treat imported coffee and the development of programs to monitor coffee pest and disease entry through unfumigated sources.” Motion seconded and approved (with dissenting votes).“
