As residue standards for agricultural products continue to rise in both local and overseas markets, traditional chemical pesticides are facing challenges. To help farmers improve crop quality and expand export opportunities, biological control solutions derived from natural soil bacteria are gradually gaining attention in Sabah. With advantages such as efficient pest control, safety for humans and the environment, and low residue risk, these solutions not only protect crop health in Sabah, but also provide key support for local agriculture to align with international markets.

Agriculture is an important economic source for many farmers in Sabah, especially vegetable cultivation. Excessive use of traditional chemical pesticides may lead to resistance and environmental pollution issues. With the increase of organic farms and eco-tourism farms in areas such as Kundasang and Mesilau, market demand for safe and residue-free pest control solutions is also rising. In addition, to meet international agricultural product standards in the European Union, Japan, and other markets, farm management has to become more stringent. Biological pesticides can help farmers meet export requirements.

Friendly to Humans and the Environment

Bacillus thuringiensis, also known as Bt, is a naturally occurring soil bacterium. Its insecticidal ability comes from the specific crystal proteins, also known as Cry proteins, that it produces. After pest larvae ingest them, these proteins dissolve in the insect’s intestine and damage its digestive system, eventually causing the pest to die.

Bt is safe for humans, beneficial insects such as bees, and the environment. It does not leave harmful residues on crops, making it suitable for organic farming or integrated pest management (IPM) systems.

Highly Targeted and Precise Control

Bt-K, also known as the Kurstaki strain, mainly targets Lepidoptera larvae, such as cabbage worms, armyworms, leafminers, and other common garden pests. Bt-A, also known as the Aizawai strain, is effective against Lepidoptera larvae and also provides good control against certain nocturnal pests, such as beet armyworms.

As a result of the collaboration between Advansia and Sumitomo, Sumitomo biological pesticides creatively combine the strengths of Bt-A and Bt-K strains. This formulation not only broadens the pest control spectrum, but also provides a longer-lasting field control effect.

The recommended dosage for Advansia’s Sumitomo biological pesticide is 20g mixed with 20 litres of clean water, sprayed evenly on crop leaves. Its stomach-poison action ensures pests ingest enough product when feeding, quickly suppressing feeding activity and reducing crop damage as much as possible.
