Pengendalian Getah Kuning Manggis Menggunakan Ekstrak Rumput Laut dan Pemupukan Kalium
Abstract: The Control of
Mangosteen Yellow Latex Using Seaweed Extract and Potassium Fertilizer. The
yellow latex disease decreases fruit quality of mangosteen because of exogenic
latex causes dirty fruit and the endogenic latex makes the bitter fruit taste,
then it does not deserve to be consumed. The causal agent of the disease was
Verticillium alboatrum, Fusarium oxysporum, and Pestalotia macrotricha. Control
using synthetic chemical for the fungus is severely decreasing the quality of
the environment, therefore the use of organic agent such as botanical fungicide
and the use of potassium fertilizer is recommended. The purpose of this
research is to find the dose of potassium fertilizer and sea weed extract to
decrease yellow latex disease of mangosteen fruit. The research was done
in-vivo in the field with indicator of the decrease of yellow latex incident.
The research showed that potassium fertilizer of 1.5 kg/plant combine with 1%
extract was the best treatment with the lowest yellow latex incident of 9.4%.
The treatment effective decreasing the disease of 56.3% compared to control and
56.9% when it is compared to 0,2% Antracol fungicide.
