Weed control in certain fruit crops has been done at the fruit crops research plantation, Dept. of Horticulture, Kasetsart University, Khampaengsaen Campus, during March to November 1983. The soil was Khampaengsaen Series with pH of 6.0-7.0 and 6.0-8.0 at the top and sub soil respectively. Herbicides were applied 1 year after the crops were transplanted. It was found that all pre-emergence herbicides did not cause phytotoxicity or reduce growth of plumello, mango and plumogranate. The application of herbicides in plumello and mango in dry season, March 1983 controlled weeds in a period of 1 to 2 month after application. However when applied in the rainy season, June 1983, herbicides provided great weed control for 5 month after application. The herbicides providing high weed control efficacy in all three crops were oxyfluorfen at 0.75 kg(ai)/ha, simazine at 1.5 kg(ai)/ha, diuron at 1.5 kg(ai)/ha or the combination of oxyfluorfen and simazine. When they were applied as high as double rate, all herbicides did not cause phytotoxicity or reduced growth.

Rambutan fruit rots and their chemical control

1985

Sirirat Sanyong

Rambutan fruits collected from 4 markets and one orchard location were left to become rotten. Isolation of the fungal pathogens from the rotten tissues revealed many fungi including Aspergillus niger group, Botryodiplodia theobromae Pat., Colletotrichum sp., Gliocephalotrichum bulbilium, Isolate 1, Gliocephalotrichum bulbilium, Isolate 2, Penicillium sp., Pestalotia sp., and Phomopsis sp. However, those fungi which were constantly associated with the rotten rambutan fruits and proved to be pathogenic were Colletotrichum sp., Botryodiplodia theobromae Pat., Gliocephalotrichum bulbilium, Isolate 1 and Gliocephalotrichum bulbilium, Isolate 2. Postharvest treatments of the rambutan fruits from the market showed that Benlate and Rovral were effective at 1,000 and 1,500 ppm. Field spray with Benlate and Rovral since flowering until harvest time resulted to longer shelf life of rambutans than the Botran and Tecto fungicides. Residues analysis of the treated rambutans by post harvest treatments were 0.057, 0.156, 0.125 and 0.823 ppm for Benlate, Botran, Rovral and Tecto, respectively. The sprayed fruits contained Benlate (0.144 ppm) and Tecto (0.0368 ppm)
