I believe you are asking if insecticides and herbicides are used as preservatives.
If so, the answer is no. Insecticides kill insects that might damage plants. Herbicides are used to kill plants ( usually as a weed control ). Both are NOT good to consume on fruits and vegetables. They are poisons.
There are lot of different forms of pyrethrum insecticide. Dusts, sprays, and coils are mostly used. If in search for organic, make sure that plants were not grown with herbicides, fungicides etc., essence wasn't extracted with hexane and that no PBO was incorporated.
GM crops are produced much like other crops, except that many that are grown have been genetically engineered to be resistant to herbicides or to produce an insecticide in the plant itself.
No a caterpillar is not a herbicide it is the common term for the larval stage of a moth or a butterfly. A herbicide is a chemical or substance that kills plant materials. Normally if you wanted to kill caterpillars you would use an insecticide.
Thus far, GMO crops are used because they are resistantant to herbicides or produce an insecticide in the crop itself. A variety of rice and a variety of banana are under development which are said to produce vital vitamins.
Biotechnology combines DNA technology and agriculture by using genetic engineering to create crops with specific traits. Currently, most are modified to be resistant to herbicides or to produce an insecticide in the plant itself.
the prefix of the word insecticide is -in
use the systemic insecticide or the common spray insecticide. but better you use the systemic insecticide.
They sprayed the new insecticide on the crops.Some insecticide is dangerous to birds.
The most effective herbicides available are systemic herbicides. These herbicides travel all the throughout the plant, including to its roots. They tend to take a slightly longer time than other herbicides but are much more effective.
Leaves of Margosa (neem) is a natural insecticide.
Raid - insecticide - was created in 1956.
