ICECRD NEWS – Biopesticides are one of the efforts to control pests and diseases that are environmentally friendly. Several biopesticides have been tested and are effective in controlling coffee pests and diseases. Along with the development of the times, nanotechnology can be applied to biopesticide formulation techniques. Nanobiopesticides are pesticide technologies consisting of small particles or small structures of active ingredients that function as biopesticides.

Pest and plant disease control using nanobiopesticides will be more effective. Some of the advantages of using nanobiopesticides are a high level of efficacy and safety, reduce the dosage or concentration of pesticide use on crops, reduce toxic residues, and reduce environmental emissions in agricultural land. There are several ways to formulate nanobiopesticides including nanoemulsion. The main drawback of vegetable pesticides containing essential oils is that they are volatile and unstable. Therefore, the active ingredients of essential oils need to be formulated in a more stable form, such as nanoparticles.

Nanotechnology can reduce particles to nano size (10-9 m) and is expected to increase the efficiency and effectiveness of the active ingredients of essential oils. Furthermore, with a touch of encapsulation, the active ingredients are less volatile and more stable. Nanopesticides consist of small particles of pesticide active ingredients or small structures of active ingredients that function as pesticides. Nanoemulsion and nanoencapsulation are one of the most widely used and effective nanopesticide techniques for controlling plant diseases.

Some of the results of research on nanobiopesticides that are effective in controlling pests and diseases include the effectiveness of a nanobiopesticide based on Bacillus thuringiensis which can cause the death of Trichoplusia ni insects up to 100%. Nanobiopestides based on clove flowers can increase the eugenol content by 9.9% and reduce the population of N. lugens and are relatively safe for natural enemies. Nanobiopestides based on clove flowers can increase the eugenol content by 9.9% and reduce the population of N. lugens and are relatively safe for natural enemies.

At the Indonesian Industrial & Bevarages Crops Research Institute (IIBCRI), initial research on the use of nano technology for the manufacture of biopesticides to control pests and diseases in coffee plants was carried out, namely the use of chili fruit extract nanobioinsecticides and nanobiofungicides using cloves. Nanobioinsecticides of chili fruit extracts and nanobiofungicides using cloves can be effective in controlling CPB pests and leaf rust at low doses. Preliminary research results have shown that Javanese chili (Piper retrofractum) extract at a dose of 2.5% -3% is effective in controlling laboratory-scale PBKo (Hypothenemus hampei) and testing of clove leaf extract (Syzygium aromaticum) at a dose of 0.2% is effective in inhibiting the germination of H. vastatrix spores. laboratory scale.

The process of making clove leaf extract in research on the effectiveness of nanobiofungicides (Syzygium aromaticum) for the control of leaf rust disease (Hemileia vastatrix). The clove leaves are dried (a), the powder of clove leaves is soaked in solvent (b), and the extraction uses a rotary evaporator (c).
