Basal Stem Rot

Stem Rot Disease Basal Stem Rot or (BSR) is a disease of the most attacking oil plants in Indonesia, causing substantial losses for farmers and planters company. Characteristics of the affected palm trees BSR is pale green leaves, leaf (young leaves) that form a little, old leaves wither and then broken, and from an infected secrete sap.

BSR disease is the usual cause of palm trees can be uprooted or broken rod suddenly, as if for no reason, so that afflict people under him could have happened to workers who are working in the oil palm plantation. Egrek pull of the trigger could be the fall of a tree, and usually leads to the workers, because the base of the stem rot disease in oil palm crops earlier. Until now, has not been found effective ways to eradicate the fungus ganoderma sp. Here you are. In various experiments in the laboratory, nearly all chemical fungicides fungus can overcome this, but not when applied in the field.

The treatment with a systemic fungicide (Tridemorph and dazomet) with an injection pressure in the direction of the root is able to limit the spread, but this method is difficult to apply because it is difficult to make sure the active ingredient is really direct root uptake.

Then developed ganoderma biological control, namely the develop natural enemies. The natural enemies of ganoderma sp. is fungus trichoderma sp. Fungus trichoderma sp. This is not harmful to plants and animals or humans, but are predators or natural enemies ganoderma sp. When viewed with a microscope, trichoderma sp. twisted and deadly ganoderma sp. within six days from the first contact.

Some manufacturers of bio-pesticide company then manufactures and markets trichoderma sp. Here you are. Some trademarks have entered into Indonesia include: production NaturalGlio NASA, the production agent MOSA, M-Dec MM production and production EvaGrow TIENS. As for how the use of bio-pesticides, it can certainly be read on the label or packaging. Important we submit, that the bio-pesticide users always abide by the rules that have been defined how to use the respective manufacturers.

In addition to using environmentally friendly bio-pesticides, can also be a way to make the environment grows ganoderma become incompatible, so that ganoderma is not or difficult to develop. Giving calcium nitrate (production Norsk Hydro, the N content of 15% and 19% Ca) can be a barrier to disease BSR, in which fungal pathogens to weaken the static and declining growth / slow.
