Abstract

A farm practice was conducted at Brgy. Katangawan, General Santos City, South Cotabato from April 11, 2013 to May 24, 2013. The general objectives of this farm practice are to document the weed problems and control practices being used by the corn farmers of Brgy. Katangawan, General Santos City and to undergo an on the job training on weed management in corn at the Pioneer Hi-Bred Research Station, Brgy. Katangawan, general Santos City where a short term research on bioefficacy of two brands of atrazine using three rates of application in controlling Eleusine indica was conducted. A survey through a one-on-one or group interview was conducted using the questionnaire that was written in English and Cebuano. There were 24 respondents in the survey who all hailed from the barangay. majority of the respondents were male, married and whose age ranged from 27-57 years old. The respondents said that they derived their income from farming. The weed specied infesting the corn fields were Ipomoea triloba, Cyperus iria, asystacia gangetica, Cyperus rotundus, Alternanthera sessilis, Imperata cylindrica, Amaranthus spinosus, Aescchynomene indica, Euphorbia hirta, Mimosa pudica and Eleusine indica. The farmers control their weed problems by using any of the following weed management option: use of chemical, mechanical, biological and cultural control or a combination of theses control optins. Handweeding is a very popular method being employes by farmers in controlling the weeds. The corn farmer of the barangay used the following herbicides: 2,4-D, Agrobound, Clear out, Round up and Atrazine. 2,4-D was a favorite herbicide. This was followed by Round up (25%0 and Clear out (18%). Agrobond and Atrazine share the same percentage usage (6% each). These data suggest that farmers probably have problems on broadleaves and sedges since 2,4-D and atrazine would control weeds classified under these morphological classification. regarding the cost of weed control, the respondents said that the biggest expense was on handweeding, P1540.00. For the chemical control, the cost was P998.33. A pictorial guide and an Herbarium of the Different Weed Species found in Brgy. Katangawan, General Santos City were likewise prepared. For the farm practice at Pioneer Hi-bred, it was found that Atrazine brand A at 12 scoops/16 li, the highest recommended rate, was the most effective in controlling Eleusine indica. Atrazine regardless of brand had a stunting effect on the weed but not on corn.
