Cassava Mozaic disease of Cassava
This disease still exists in the district but it is no longer a threat in that varieties that are resistant to it have been developed that are resistant to the disease. The pockets that still exist are for those farmers who prefer the taste of those old susceptible varieties and they would rather harvest little but when they have got some tasty food they want
Cassava Brown streak virus
The disease is still a big threat to the food security of the district. National Agricultural Research Organisation has developed a number of varieties which at first seemed to be resistant/tolerant but in Iganga district many of them have succumbed. This disease has caused yield losses of up to 90% in gardens where the attack has been seriuos. Currently there is only one released variety which is fairly resistant, though really just tolerant, called NASSE 14. Unfortunately the variety is in short supply in the district. Operation Wealth Creation supplied this variety to farmers in the first season of 2015, a consignment of 241 bags but this was a drop in the ocean. This consignment is now multiplying as the first crop has matured and is or has been harvested.
The current programs to increase the supply of the variety is by the Ministry of Agriculture Animal Industry and Fisheries through the Buginyanya Zonal Agricultural research Institute which will be providing multiplication sites of 1 acre per parish in the whole district.
Maize Lethal Necrotic disease
This is a new disease of maize It attacks maize at any stage of growth. When the attack occurs when the maize is still in the active growth (before flowering) there may be total loss. The disease has been identified in Nawanyingi sub county in a village called Bukonko, In Nakalama sub county in a village called Bukaye, In Buyanga sub county in a village called Buwaya and in Namungalwe sub county in a village called Namunkanaga and in Ibulanku sub county in a village called Buniantole.

The situation is not alarming yet as the surveillance is done quarterly and the necessary action is taken to contain the disease
Coffee twig borer
This is also a new insect pest of coffee. The adult insect bores into the young developing shoots, makes a tunnel inside the shoot and then lays the eggs at the end of the tunnel. The effect of destroying the tissue during the tunneling is the one which make the shoot to die and dry. The pest has spread throughout the coffee growing parts of the district. The interventions which have been done by the department is to sensitise the coffee growing population of the problem and to make them understand the mode of attack and how the pest reproduces. Recommendations for control have then made known to farmers of;
• To remove the shots which are drying so as to destroy the young developing insects which were laid in the tunnels inside the shoots
• To spray with a chemical called Imax so as to reduce the population of the adults which do the laying of eggs into the tunnels.
• Observation also reveals that despite the control measures that are being recommended to farmers, the rate of containment of the pest may not only be attributed to the recommendations. There are seasons when one hardly sees the pest and the yields for coffee are quite good. It may require to establish whether the pest may be having a natural enemy which may be controlling the pest population
Soya bean Caterpillar
This is an insect pest which attacked soya beans once in the season B of 2015. The insect pest was new and it had never occurred before. It was peculiar in a sense that soya beans is a crop which has not been having insect pest problems. A very fatal attack was found in Buyanga sub county in Kiwanyi parish , initially in a 10 acre soya bean field and later in scattered fields in the parish, where leaves, young developing pods and young shoots were being eaten up by the caterpillar. The damage by the time of intervention was already 50% but the caterpillars were still young and actively eating. If they were left to complete their life cycle the damage would reach 100 %. Later the pest was identified in Bubenge village in Igombe sub county in Nakalama sub county opposite Nakalama Primary school. The incidence was reported to the Ministry of Agriculture, Animal Industry and Fisheries which responded by providing Chemicals which were given to farmers to spray. The pest subsided as a result of the intervention but since then the department has been on the lookout for the pest outbreak.
