Anti-microbial Performance of 3-Iodopropinyl-NButylcarbamate (IPBC) in Poly(lactic acid) Added with Calcium Oxide (CaO) for Agricultural Applications

Abstract

This study investigated the effectiveness of fungal antifungal treatment by mixing polylactic acid (PLA) with 3-Iodo 2-propinyl butylcarbamate, (IPBC) and Calcium Oxide ( CaO) for application A mixture of IPBC. The addition of IPBC of 2. 5, 5. 0, 7. 5 and 10. 0 ppm into polymer. The polymer compounds were mixer by internal mixer follow by extrusion to produce the specimens. An anti- microbial activities were tested by 2 methods, which are Disk Diffusion Test Dry Weight technique. It was found that, PLA added with CaO and IPBC varies 2. 5, 5. 0, 7. 5 and 10. 0 ppm showed an effective inhibition of fungal growth by the more IPBC the more inhibition zone. The real usage of compounds was test by put the compound into tomatoes plants, which were 1- 7 cm weight. The results showed that, the small size of tomato tree were died after 5 days. Moreover, the compound with CaO die faster 9 days and slow down the growth of death tomato tree.
