Scientists prove that Argel is an effective pesticide and fertilizer


(MENAFN- Sudanow Magazine) KHARTOUM (Soudanow) – In a great Sudanese scientific achievement, two professors from the Sudanese University of Science and Technology were granted a patent for the use of the leaves, branches and stems of the local herb hargel (scientific name Solennostemma argel) as an effective stimulant for crop growth and also as an organic pesticide for certain weed diseases.

Observers view the discoveries and the patent as a milestone in Sudan’s agricultural progress.

The patent was awarded by the Registrar of Intellectual Property of Sudan to Professor Awad Khalafalla and Professor Alsir Ibrahim Mohammad Idris of the Research Center, College of Agricultural Studies of the University. The patent took the number 3144.

Sudan intellectual property titled the patent as: Scientific patent on the use of Argel shoots (Solennostemma argel) as a growth and yield bio-stimulant and bio-pesticide on horticultural crops.

According to his abstract, the study “was based on preliminary observations on the aforementioned properties of Argel. A series of experiments were carried out to prove the validation of these hypotheses. Very significant growth and yield gains were obtained in crops treated with Argel as a foliar spray of water at low concentration or as a direct addition to the soil in small quantities. Increased yields have been reported for date palms, mangoes, bananas, okra, field and greenhouse tomatoes, as well as the disappearance of harmful threats from pests and diseases.

This could be a tool for organic production to avoid the health risks of agricultural chemicals. “

For further explanation, Sudanow contacted Dr Awad Khalafalla Taha, Professor of Plant Protection at the College (M.Sc. and PhD from Newcastle University – UK) who said the idea arose out of extensive research aimed at finding effective means against parasites which at the same time do not harm humans or animals and which are safe and friendly sources for the echo-system.

In the past, most pest control was carried out through the use of chemical pesticides due to their direct effect on killing pests, but due to the heavy use of chemical pesticides it has become evident that these chemicals have negative effects represented by poisonings. in humans, animals and plants in addition to their harmful effects on the ecosystem.

This is where the idea came from to find alternative natural killers for the different types of parasites.

It has been discovered that a chemical pesticide which used to give 100 percent results in killing pests has now installed no more than 20 percent in pest mortality. For this, the idea of ​​researching alternative ways and means of pest control emerged. These means included the use of different plant extracts either in the form of dry powders, liquids or gases.

Previously, Sudan had tried using different plants to control pests. The plants used in this business included neem (azadirachta indica), argel, camphor, spearmint, garlic, and others. The results of these studies had stimulated the creation of this natural organic pesticide from the argel plant which grows wild in all parts of Sudan. It can also be cultivated.

Professor Taha said that by applying the herbal extracts of argel, he realized that it had an antiparasitic effect. After conducting several experiments on a number of agricultural pests such as peanut and bean beetles, he found that argel has an effect equal to that of permitted chemical pesticides. But the cost of the pesticide extracted from the clay was only five percent of that of chemical pesticides.

He also used the extracts of argel to control disease-carrying pests like Anopheles, which carry malaria, and carriers of elephantine and yellow fever.

In these cases, the effect of argel extract was equivalent to that of chemical pesticides, but with a huge difference in financial cost. Another advantage of argel extracts is that they can be prepared and used by the farmer on their own and inexpensively.

Professor Khalfalla said that experimentation with plant extracts to kill pests has been going on for many years now at Shambat Agricultural College here. At each stage, College researchers would discover new plants that have a beneficial effect on pests. He paid tribute to his fellow researchers and technicians from the College and the National Research Center who cooperated with them in this research.

We hope to be able to establish a central laboratory for the chemical analysis of the effective components of the different plants and to prepare liquid, powder and gas extracts of the plants, he said, concluding that their goal was always to provide natural products. Low cost. and environmentally friendly means for pest control.
