Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the 14-alpha demethylase enzyme from demethylating a precursor to ergosterol. Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth ...
The diseases often kill seeds before they grow. However, if the seeds do manage to sprout they demonstrate symptoms almost immediately. The stalks of the cotton plant will be weak, brown sunken lesions will appear on the stem, and the plant will often die before producing or will have very poor yields. [ 74 ]
Like other pesticides, fungicides are numerous and diverse.This complexity has led to diverse schemes for classifying fungicides. Classifications are based on inorganic (elemental sulfur and copper salts) vs organic, chemical structures (dithiocarbamates vs phthalimides), and, most successfully, mechanism of action (MOA).
This is a list of fungicides.These are chemical compounds which have been registered as agricultural fungicides.The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1]
Thiram was therefore developed as a seed treatment in the 1940s to extend the spectrum of diseases that could be controlled. [6] In 1949 ICI commercialised a seed treatment with trade name Mergamma A, containing 1% mercury and 20% lindane, an early example of a product designed to protect the seed from both fungal and insect attack.

Monsanto's seeds are expensive and lose vigour after one generation, prompting the Indian Council of Agricultural Research to develop a cheaper Bt cotton variety with seeds that could be reused. The cotton incorporated the cry1Ac gene from the soil bacterium Bacillus thuringiensis (Bt), making the cotton toxic to bollworms.
Dysdercus cingulatus is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. [1] It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton-staining fungi as they do so.
Orbit (propiconazole) is the most effective fungicide available. [4] Spray recommendations depend on the previous year's disease pressure. "If disease pressure was low to moderate (fewer than 15% of berries infected), two fungicide applications are recommended: one at 10 – 20% bloom and again 7 – 10 days later.
