©RSB 2023  - All rights reserved                  8 
 4.5.2.2  Physical analysis  
4.5.2.2.1  The general appearance of the products shall be checked during the process of unloading; if the 
seeds are moist, insect infested, insect damaged, or contain an unusual amount of dirt, debris or other foreign 
material.  
4.5.2.2.2  If the observations from physical analysis do not allow taking the decision, a sample from the 
suspected lots shall be taken and accurate tests conducted before any acceptance of the lot.  
4.5.2.3  Drying  
4.5.2.3.1  If seeds brought to the warehouse do not comply with maximum moisture content stated in relevant 
Standards, the seeds shall be dried and moisture content reduced to the specified level.  
4.5.2.3.2  If heated air is used for moisture reduction, temperature and drying time shall be synchronized so 
that they do not result in adverse effect on quality of the seed.  
4.5.2.3.3  If drying is done under the sun, drying should be held on plastic sheets, preferably black. The seed 
should be spread in a thin layer and raked at intervals, to remove the evaporated moisture.  
4.5.2.3.4  Whatever the drying system, care shall be taken to avoid attack by insects, rodents,birds and 
foreign matters.  
4.5.2.4  Screening, sorting and grading  
4.5.2.4.1  Seeds shall be screened, sorted and graded according to relevant standards prior to warehousing.  
4.5.2.4.2  Seeds shall be screened and/or aspirated to remove all defective seeds, noxious weed seeds,  
vegetable matter,  seeds other than the main constituent seed, straw and chaff.  .  
4.5.2.4.3  Screening shall be done in such way as the operation does not pollute the surrounding places.  
4.5.2.4.4  Sorting shall be performed before any seed treatment to ensure the removal of defective seeds.  
4.5.2.4.6  Containers of defective seeds shall be removed as soon as practicable from the warehousing area.  
4.5.3  Seed coating  
4.5.3. 1 Only approved chemicals shall be used for seed coating.  
4.5.3.2   Records for chemicals used shall be retained.  
4.5.3.3  Appropriate techniques shall be deployed to keep quality of seeds after coating.  DRS 566: 2023  
9                ©RSB 2023  - All rights reserved  
 4.5.4  Loading and unloading  
4.5.4.1  Loading and unloading may be done mechanically or manually.  
4.5.4.2  If manual loading and unloading is used, the floor should be 1m above the ground to permit easy 
loading or unloading into trucks at the sides of the warehouse.  
4.5.4.3  Loading and unloading shall not take place in open area when it is raining. A canopy should be 
constructed over every entry door to allow continuous loading and unloading even when it rains. Maximum 
package weight shall be of 50 kg where human loading and  offloading is involved.  
4.5.4.4  Loading and unloading shall be done in a way that does not affect the quality of seeds.  
4.5.5  Provision of spacers  
4.5.5.1 The spacers /pallets shall be used to avoid the sacks being in direct contact with the ground and 
shall be strong enough to resist the weight.  
4.5.4.2  Spacers should be standard pallets, of manageable size, and therefore easy to lift. They shall be 
treated with pesticides and stacked neatly when not in use.  
4.5.6  Stacking  
While deciding the whereabouts of bag stacks the following shall be considered:  
a) Containers of seeds in each lot shall be stacked in basic patterns of cluster formation so they can be easily 
counted and quality maintained; where necessary, potato seeds should be bagged.  
b) stacking around pillars shall be avoided, as this makes inspection and fumigation difficult, and it can damage 
the building;  
c) the  stack shall be built at least one (1) meter away from the walls of a store. This allows easy inspection, 
prevents moisture ingress from contact with the wall and facilitates fumigation treatments  
d) gangways leading to the doors shall be at least one (1) meter wide to allow for proper inspection and 
spraying. An inspection walkway shall always be left between stacks;  
e) the  stack shall not be built too high and not closer than 1.5 m to the store roof beams so that staff can work 
on top of stacks;  
f) when using jute or sisal bags the stack can be built to around 18 - 20 layers, any higher then there is a risk 
to stability and it is difficult for storage workers. When using polypropylene or plastic bags the stack heights 
shall be lower as they are less stable than jute or sisal;  
g) different commodities, different consignments (new and old) shall be placed in different stacks, i.e. 
separated in batches based also on the time of their reception in store, as far as the available space will 
allow.

 4.5.7  Pests prevention and control  
4.5.7 .1 Warehouses shall be free from live and dead insects and vermin.  
4.5.7.2 Pests can be prevented and controlled by:  
a) keeping seeds below the temperature or the humidity necessary for increase in pest numbers (for example 
drying, aerated storage, refrigerated storage);  
b) spraying the floors and walls with approved pesticides;  
c) dusting of seeds by approved pesticides;  
d) by fumigation; and  
e) by using rodent baits.  
4.5.7.3 Where control is by fumigation the following provisions shall apply:  
a) approved fumigants shall only be used by properly trained and authorized persons/organizations who 
understands the dangers and the necessary safeguards;  
b) there shall be no human habitations within close proximities of the planned fumigation; if there are, the 
arrangements shall be made for people to be relocated during the treatment;  
c) fumigated piles shall be kept closed and post warning signs displayed until the gas concentration is below 
the concentration which does not cause any effect to the workers;  
d) the stacks shall be well sheeted and there shall be no store imperfections, e.g. cracks in the floor, unfilled 
floor joints, roof leaks etc., which might jeopardise the success of the fumigation; and  
e) at the end of the fumigation, warehouse shall be aerated carefully to minimize dangers.  
4.5.8  Record keeping  
Warehouse shall keep records of:  
a) origin, and volume of each lot of seeds kept;  
b) laboratory tests carried out;  
c) names of chemicals used  such as for pests control and coating;  
d) fumigation details: fumigant used, the date and method of fumigation;  
e) names of employees and training undertaken;  DRS 566: 2023
