Metribuzin is a photosynthetic electron transport inhibitor
at the photosystem II receptor site. Selectivity is due to
metabolism (mostly conjugation) within the plant.
Metribuzin is a selective systemic herbicide, absorbed
predominantly by the roots, but also by the leaves, with
translocation acropetally in the xylem.It is pre and post
emergence control of many grasses and broad-leaved
weeds in soya beans, potatoes, tomatoes, sugarcane,
alfalfa, asparagus, maize and cereals. It inhibits
photosynthesis.

Nearly 55 per c ent of the world population
depends on wheat for about 20 per cent of
calories intake. It is one of the major food grains
of the country and a staple food of the people of
North India, where people have preference for
chapatti. The diverse environmental conditions
and food habits of people in India supports the
cultivation of three types of wheat (bread,
durum and dicoccum). Among these, bread
wheat is contributing approximately 95 per cent
to total production while another 04 per cent
comes from durum wheat and close to one per
cent from Dicoccum.

the beginning of India’s agricultural age.
Soybean has established itself
as a major rainy season crop in

Tomatoisoneofthemostimportantvegetable
worldwide. Tomato is one of the most
important “productive food” because of its
unique nutritive value. It is one of the most
versatile vegetables with administered usage
in India culinary tradition. As it is a relatively
short duration crop and gives a high yield, it is
economically attractive, and the area under

Tomato is heavily infested with weeds from time it is
sown till harvesting. This is because of frequent rains
encourages several flushes of weed, hot and humid
climate congenial for the growth of weeds especially
grasses. Tomato yield was reduced as much as 25-60%
duetoweedinfestation.
