Scientists at the University of Vienna in Austria have introduced a cost-saving and less polluting pesticide spray method that fills empty shells of dead bacteria with chemical pesticides and sprinkles them on the foliage of plants. The pesticides sprayed by this method can not be washed away even under heavy rain, which can improve the efficiency of pesticide use, save costs and reduce environmental pollution.
Insecticides that have been sprayed on crops in the past are easily washed away when it rains. In order to ensure the insecticidal effect, it is necessary to repeat the spraying frequently. This wastes and increases the pollution of soil and water by pesticides. .
Scientists have chosen a bacteria that attaches to plants and extracts a protein from the bacterial-infected virus, the bacteriophage virus, to treat the bacteria. Protein can make a small hole in the outer shell of the bacteria, penetrate deep into the bacterial cells, damage the cytoplasm and nucleus, leaving only one empty shell. The researchers filled the bacterial shells with chemical pesticides and sprinkled them on the plants of barley, cotton, corn, cabbage, rice and soybeans, and washed them with artificially simulated heavy rain. It was found that there was still 10% after the "heavy rain". 55% of the bacterial shells were not washed away. Among them, the bacteria stored on rice have the largest shells and the least on soybeans. (China Pesticide Information Network)
