According to the US Department of Agriculture, in developed countries up to 25% of the total harvest is lost due to weeds and other pests, in third world powers up to 50%. And this is only because the production and use of pesticides is put on stream, and if not for them, people would receive less than a third of the plants grown. But the harm from pesticides is enormous, so the best minds of mankind are fighting over their replacement, and now they are proposing to use genetic weapons.
Scientists from Helsinki have created a biopolymer based on the RNA of the pest, which is structurally identical to its DNA, but filled with "bugs" and "glitches" to use the slang of programmers. This is not a toxin, but a kind of saboteur - the biopolymer will interact with the DNA of the attacked organism in the process of gene replication, but due to its damaged structure, it will not be possible to correctly assemble the required protein from amino acids. The process of cell reproduction will stall and the living creature will die.
The bipolymer with decoction RNA interacts only with the genes of a specific pest, it is harmless to the cultivated plant itself and other animals in the fields. This is a one-time weapon that quickly decomposes in the natural environment, and does not accumulate, unlike pesticides. Scientists do not hide the fact that the idea of genetic sabotage was spied on by nature itself and simply adapted it to the needs of agriculture.
One problem is that farmers need tons of protective equipment, and the biopolymer has so far been created only in laboratory conditions and is very expensive to manufacture. Therefore, all hope for bacteriophages is a kind of virus that generates their own parasitic RNA in order to insert into other cells and infect them. You just need to teach bacteriophages to create the "correct" RNA, and then we will have a farm for growing genetic weapons.
