The reason for the resistance of the herbicides is the use of pesticides in high concentrations, which caused a gradual resistance to pesticides by the jungle plants, a line in which many farmers fall into the goal weed control

Its really needs to manage herbicides resistant weed otherwise they become super weeds.

Mohammed Akram Alobaidy Thank u sir

We need to reduce the application of high dosage of herbicide and embrace integrated farming, precision and eco-friendly agricultural practices.

Dear Uma Nath Shukla Integrated weed manaagement strategies need to be followed; this will lessen selection pressure induced due to application of higher dosage of weedicides on weed flora. The second approach may relate to diversifying the mode of action of herbicides. The third approach may be to use bioherbicides. All these approaches are likely to retard the development of herbicide resistance in weed flora.

Thanks!

To know about herbicide resistance, we should have the clarity on our mind about the difference between herbicide tolerance and herbicide resistance. HT is the inherent ability of a biotype or species but HR develop gradually with natural selection or mutation.

As prevention is better than cure, so this is our responsibility as a weed scientist or an agronomist that we shouldn't let HR develop in the field. To prevent the HR, we shouldn't use same group of herbicide again and again, we should integrate different weed management practices (IWM) i.e. cultural, physical, biological and chemical. Only thinking on this we can't help much, rather we have to reach to more farmers and we may spread awareness about what HR is, how it develop, what are the consequences and how they can prevent or manage it.

Completely based on my understanding.

Any practice with mono character always endanger for the sustainable agriculture. As for Herbicide resistance we need diversification in to the field as well as in weed management practices. moreover, farmers and other stakeholder does not take the technical inputs in their course of action resulted many aberration in to field eg. higher dose, faulty spraying ways, lack of skilled person, wrong calculation of doses and at last not aware of what and how exactly they increase the danger of HR.

There are currently 521 unique cases (species x site of action) of herbicide resistant weeds globally, with 263 species (152 dicots and 111 monocots). Weeds have evolved resistance to 23 of the 26 known herbicide sites of action and to 164 different herbicides. Herbicide resistant weeds have been reported in 94 crops in 71 countries.
