Гербициды — химические средства борьбы с сорняками. Часть вторая

Become a member By destroying most weeds through direct contact, it quickly deactivates in the soil, which is very important from an environmental point of view.When using paraquat, cereals can be sown into the soil treated with it with non-moldboard plowing. Trifluralin, which has been used since the early 60s, is today one of the most important in the class of dinitroaniline herbicides.

It is used to control annual grasses and broadleaf weeds on cotton plantations, soybeans and other crops.Chloroacetyl chloride-based herbicides appeared in 1965. One of the representatives of this class of compounds is propachlor.Such herbicides are used for the pre-emergence destruction of grasses and some broadleaf weeds in wheat and vegetable crops.In 1971, aminopropionate herbicides were used for the first time.The first of these was benzoylpropethyl.Others followed, including flampropisopropyl, which can exist as a mixture of spatial isomers.In many cases, only one of these isomers exhibits biological activity, since the configuration of the other isomer does not allow it to act on the receptors of the weed.The active isomer of flampropisopropyl, which is an industrial herbicide, is at least twice as active as a mixture of isomers.It will be recalled that it is very difficult to develop an economical method for obtaining a specific spatial isomer.Dichlofopmethyl was used in the mid-70s mainly to combat various grasses in cereals, sugar beets and other crops.At the same time, alloxydim-sodium found application for the same purposes.In the early 70s, glyphosate (N- (phosphonomethyl) glycine) was first used.It turned out that it has a very broad spectrum of activity for post-emergence use.

The herbicide is rapidly deactivated by most soils and practically does not exhibit toxic effects on mammals, insects and bacteria.These qualities allow it to compete with paraquat in a number of situations, however, most likely, these two herbicides complement each other.Glyphosate is quickly transferred to all vital tissue organs and effectively destroys various perennial grasses with a deep root system (wheatgrass, sedges and broadleaf weeds), in the fight against which paraquat is not so effective. where to advertise online casino
