Prof. Dadang Hermana: Vegetable and Biological Pesticides Can Be an Environmentally Friendly Alternative for Pest Control

The use of pesticides is often applied not only in the agricultural industry, but also in households. However, most people still depend on synthetic pesticides. In fact, there are many alternatives to pesticides that are environmentally friendly and relatively safe.

Prof. Dadang Hermana, Professor of IPB University from the Department of Plant Protection, Faculty of Agriculture, explained the proper, effective, and efficient application of biological and vegetable pesticides. He said people should not have the wrong perception, biological and vegetable pesticides are actually very different. Because most of these two pesticides are misunderstood.

“Biological pesticides involve the use of microorganisms in their entirety. Both bacteria, fungi, nematodes, and other microorganisms. On the other hand, botanical pesticides use plant extracts or chemical compounds in plants as active ingredients," he explained in the Propaktani Webinar "Appropriate Use of Pesticides for Control of OPT Food Crops" organized by the Indonesian Ministry of Agriculture, (02/12).

He continued that the process of extracting chemical compounds from plants is highly dependent on the materials used. Because not all plant chemical compounds are soluble in water or ethanol. This is closely related to the solvent used.

According to him, botanical pesticides provide biological activity that is not only killing pests. This pesticide can also suppress pest egg production and interfere with skin turnover. However, the desire of the community in general is to eradicate pests completely. Whereas in the future, the use of botanical pesticides will also reduce the number of pests gradually.

He added that the most important thing in the plant extraction process is efficiency. Extraction of plant material is recommended not excessive and exceeds the requirement. Excessive use of plant extracts will lead to the possibility of poisoning in plants or phytotoxic.

"This use is an opportunity for us to use these plant-based pesticides, firstly because of the side effects of using synthetic insecticides," he said.

According to him, the use of botanical pesticides is an alternative solution to insecticides that are more environmentally friendly. This action is an implementation of IPM (Integrated Pest Control) technology which is more environmentally sound. Moreover, because of the market demand for organic products and international issues related to pesticide residues.

“For example, if the use of synthetic pesticides two weeks before harvest is stopped, the question is whether it will be safe to leave it for two weeks. Of course, we can exchange this control with the use of vegetable pesticides which are more easily degraded so that when exported, the residue will be low,” said Prof. Dadang.

He added, many opportunities can be explored from the use of these pesticides. The exploration process of plant material can take advantage of various local plants and plants known to have medicinal properties. Ecological aspects can also be used as a basis in the exploration of plant material. The formulation of this pesticide must be carefully considered in order to ensure the ease of application and safety of the product.

Meanwhile, the types of biological pesticides, he added, work specifically and how they work depends on the type of microorganism. Generally, it takes longer to kill the host. However, this pesticide is relatively environmentally friendly, efficient and can synergize with other IPM strategies.

“If you want to make biological pesticides, make the correct Standard Operating Procedure (SOP) because later it will be related to product consistency. So, the formulation is good, the efficacy is good, and the safety is good,” he said regarding the quality of pesticides in the market that often changes. (MW/Zul) (IAAS/FJN)
