Abstract
The major practice was conducted at the Bayer CropScienceAD-SEA at Brgy. Masiit, Calauan, Laguna from 11th of April 2014 to the 13th of June 2014. The main objectives were: (1) to apply the agricultural knowledge learned from the university; (2) to learn the basics of research work and (3) gain actual experience in the conduct of efficacy trials of herbicides. Efficacy of new compounds (Annie, Bonnie and Connie) was compared with a market standard. The phytotoxic effect of a herbicide (Donnie) due to persistence on pole sitao and bitter gourd planted at different times was assessed;it was applied at two different doses. The effect on root and shoot length of a systemic insecticide applied on pre-germinated rice seed was also evaluated.Therewere no discernible trends observed within the dosages of a compound. Also, based on the results of the latter two observation periods, Annie (SC) was no more effective in controlling weeds than Annie (WP).Donnie did not in any way reduce emergence of pole sitao and bitter gourd. The experiment though, was destroyed by typhoon Glenda. A significant increase on the shoot length was found in the treated rice at 7 DAA.This advantage, however, did not persist until the 14th DAA but provided protection against brown plant hopper infestation.
