Which herbicides are seedling growth inhibitors? - Correct Answer ✔
️✔️Dinitroanilines: (a) Treflan (b) PreM (c) Balan (d) Surflan
Acetanilides: (a) Pennant
Thiocarbamates: (a) Eptam
Benzamides: (a) Gallery
Nitriles: (a) Casoron, Norosac
, Which herbicides are photosynthesis inhibitors? - Correct Answer ✔
️✔️Triazines (a) Prometon
Phenylureas: (a) Tupersan
Benzothiadiazoles: (a) Basagran
Which herbicides are cell membrane disruptors? - Correct Answer ✔
️✔️Bipyridilliums: (a) Diquat d) Formulation types
What are adjuvants used for and what different types are there? -
Correct Answer ✔️✔️They increase herbicides effectiveness.
They can also affect selectivity.
There are surfactants, which help the chemical stick to a waxy leaf (by
decreasing the surface tension). There are also buffers, which help
adjust the pH (the acidity) of the chemical to make it more like water.
