Abstract

The use of overdoss insecticides by farmers has negative effects for environment, plant target, consument and at the end the farmers themselves. Periodical spraying of the insecticide almost in all plant growing period including during the flowering phase can affect the reproduction organ and decrease its productivity. The objective of the research is to assess the effect of the insecticide spraying containing bioactive profenofos to pollen viabilitity and productivity of tomato (Lycopersicum esculentum Mill.) as well as to determine the insecticided containing bioactive profenofos that decreases the pollen viabilitity and productivity of tomato. The research is arranged in Completely Randomized Design (CRD) with four replications. The insecticide concentrations used are 0, 1, 2, 3, 4 ml/l, respectively. The parameters observed are pollen diameter, pollen germination percentage, and fruit number. The data is analyzed by Anava and continued by LSD at 6 = 0.05 to analyze differences between the treatments. The results show that the insecticide spraying does not influence the pollen size but significantly affected the percentage of pollen germination and fruit number. The pollen diameters obtained from 0, 1, 2, 3, 4 ml/l are 22.6, 21.4, 20.6, 22.4, and 20.9 6m respectively, while the pollen germination percentage are 91.0, 86.8, 80.4, 67.7, and 54.4 %, and the fruit numbers are 23.3, 21.3, 16.3, 13.8, and 8.8 respectively. The conclusion is the insecticide spraying inhibites pollen germination and decreases the fruit number of tomato.
