The price a farmer
attains at the selling floors is determined among other factors by the seed one
sows hence farmers are urged to use certified seed as maintenance of genetic
purity in seed is the primary objective of seed certification.
This suggest that
the all seed contained in a seed lot is homogeneous and contains no seed of
another variety or type.
The certification
process provides strict standards for seed production that seed producers follow.
These standards
include for example, the producer’s registration for multiplying and selling
tobacco seed according to local regulations as well as field and packing facility
inspections.
In addition, every
lot produced must pass a laboratory test.
Consequently, it
is important that farmers purchase certified seeds as non-certified seeds may
lead to poor yield as they can carry certain diseases that can be seed-borne
and this may cause the leaf to be infected.
Not every tobacco
seed variety does in every part of the country therefore tobacco farmers are
encouraged to consult AGRITEX, Tobacco Research Board (TRB) or TIMB and tobacco
contracting merchants in case of contracted growers for most suitable varieties
for their areas.
It is worth noting
that variety selection is the foundation for achieving the market desired
tobacco leaf quality, subjective characteristics as well as for optimizing
farmer yield.
Tobacco
producers need to meet the requirements of the buyers which are physical and
chemical integrity, if their efforts are to translate to profits.
Physical
integrity is achieved by delivering to the market a product that is free from
non-tobacco related material (NTRM) such as grasses, feathers, plastic, and
string amongst other materials while chemical integrity of the leaf has more to
do with reduction in pesticide residues, correct concentrations of nicotine, minimizing
tobacco-specific nitrosamines.
There
is constant monitoring by tobacco buyers, TIMB and customers to ensure the
integrity of the product.
To
achieve the required integrity, it is of utmost importance that farmers adopt some
of the following agronomic measures throughout the season.
Tobacco, like any
crop, needs to be protected from pests and diseases and a variety of techniques
are promoted to prevent or suppress crop pests and disease that gives priority
to the use of physical, mechanical, cultural, and biological control methods,
and the least possible use of agrochemicals.
These methods
include use of resistant varieties, crop rotation, use of attractant or
repellent plants, and destruction of crop residues.
Integrated Pest
Management (IPM) is the best practice to use as it emphasizes also a biological
approach by sequencing preventive and control measures that impose the least
environmental impact.
These programs are
based on identifying pests and diseases and beneficial organisms or cultural
techniques adapted to local conditions and establishing economic threshold levels
to determine what treatments are necessary to reduce risk of financial loss.
Farmers are
expected to apply Crop Protection Agents (CPA)/chemicals as a last resort and
only as a result of monitoring and scouting when the corresponding economic
threshold levels have been reached.
Monitoring and
scouting must be done on all tobacco farms.
Monitoring and
scouting involves recording pest and beneficial insect numbers across the
tobacco field for a reliable estimation of the potential economic impact of
damage from the pests.
Recording pest and
beneficial insects’ numbers in the field can also help define the appropriate
non-chemical control methodology if required.
If chemicals or
CPAs are being used, it is advised to only use products that have been approved
by Tobacco Research Board (TRB) and gazetted by TIMB.
When using
chemicals, farmers should follow the correct timing and dosage recommendations
which are always indicated on the product label, warning label and instruction
manuals.
Farmers should shy
away from purchasing chemical products that have not been approved by and bearing
a TRB registration number.
When in doubt,
farmers are advised to consult TRB, TIMB or AGRITEX.
As rule of the
thumb, growers are encouraged to rotate crops as it is essential to break pest
and disease cycles and to maintain or improve fertility.
Farmers are
encouraged to destroy seedbeds after transplanting as the tobacco plant Pests
and Disease Act (Chapter 19:08) stipulates that all seedbeds should be destroyed
by 31 December of every year and field crop residues after harvest.
Destroying seedbeds
and crop residues which are, stalks and roots, must be undertaken in a timely
manner after the production cycle has ended to limit the potential for pest and
disease transmission.
It
is important to control weeds proliferation until the end of the harvest as
doing this assures greater productivity, better quality as well as reducing
foreign material.
Contrary
to some farmers’ thinking that some section of the production process matter
more than others, the Tobacco Industry and Marketing Board urges farmers to
give equal weight to all processes from selection of seed variety, buying
certified seeds right through to marketing and presentation as they all have a
bearing on profit margins.
