Scientific name

As the stem elongates, smaller, narrower and less dissected leaves are produced alternately on the pubescent, rigid, angular, longitudinally-grooved stem, which becomes woody with age. Both leaves and stems are covered with short, soft trichomes, of which four types have been recognized and are considered to be of taxonomic importance within the genus Kohli and Rani, Flower parthenium hysterophorus are both terminal and axillary, pedunculate and slightly hairy, being composed of many florets formed into small white capitula, mm in diameter.

This process continues in cyclic fashion until the bioagent and weed population get established at a low level. A successful control strongly parthenium hysterophorus on favourable conditions for the bioagent, which effectively increase the population of the controlling organism [ 40 ].

This method is a slow operation and currently used in noncropped areas. The control of different weeds through the use of classical biological agents, insects, and fungal plant pathogen is given in Table 2 [ 3041 ].

Successful examples of control of weeds through classical biocontrol agents. Usually, they are applied in a manner similar to chemical herbicides hence called bioherbicides by periodic dispersals of distinct doses of the virulent inoculum [ 37 parthenium hysterophorus, 43 ].

The concept of mycoherbicides was introduced by Daniel et al.
