- WEEDS are the plants,
which grow where they are not wanted. They grow in thefields where
they compete with crops for water, soil nutrients, light and space
and thus reduce crop yields.
- The controlling of
weeds in the growing crops with weedicides increases their yields
and ensures the efficient use of irrigation,fertilizers and
plant-protection measures, such as the spraying of insecticides and
fungicides.
- Both the nature of the
weeds and that of the crops which they infest, influence the action
of the weedicides. For example, the same types of weeds occur in
maize and cotton which are kharif crops. 2,4-D can be used for
killing the weeds in maize, but this weedicide should never be used
on cotton which is highly sensitive to it.
- A series of field
trials were conducted to evaluate the effect of newly introduced
weedicide against broad leaved weeds of wheat crop at Adaptive
Research Farm.
- To manage the weeds in
direct seeded rice, four weedicides were tested and compared their
efficacy with handweeding. Among the weedicides Nominee 100SC (bispyribac
sodium) and Sunstar Gold 60WG (Ethoxy sulfuron) proved as the best
weedicides with 90.5 and 87.19% weed control respectively.
- The on-line automated
weedicide sprayer system was developed at Universiti Putra Malaysia
to locate the existence and intensity of weeds in real-time
environment and to spray the weedicides automatically and precisely.
- To asses the effect of
pre emergence weedicide on adsorption and desorption in inceptisol
soil four pre emergence weedicide used viz., oxyfluorfen, alachlor,
fluchloralin and pendimethalin, in different concentration.
- Some of the weedicide
effect can be lost over the winter months and can offer less weed
control in the first summer when compared with Post-planting
applications in the spring.
