Crops
For each key crop in Uganda, find the main threats, the recommended products and the protection calendar.
Our crops
The recommendations below are based on our catalogue and the uses on the label. Adapt them to your area, your variety and the pest pressure you see in the field.
Our crops
Tree and plantation crops
The coffee berry borer (Hypothenemus hampei) reduces both yield and bean quality; sanitary harvesting, trapping and well-timed protection after flowering are essential.
Main threats
Recommended products
Fruit crops
Nematodes (Radopholus similis), the banana weevil and black Sigatoka are the major constraints; clean planting material is the first line of protection.
Main threats
Recommended products
Cereals
Fall armyworm and stem borers attack from the earliest stages; early weed control, up to the 8-leaf stage, is decisive for yield.
Main threats
Recommended products
Roots and tubers
Weed control during the first three months is decisive; healthy cuttings limit cassava mosaic disease, and mealybugs and green mites need watching in the dry season.
Main threats
Recommended products
Cereals
Weeds (grasses, sedges and broadleaves), rice blast and stem borers are the main yield-limiting factors in both irrigated and upland rice.
Main threats
Recommended products
Cereals
Hardy cereal of semi-arid zones, from the Sudano-Sahelian savannahs to the drylands of East Africa, sensitive to early weed competition, stem borers, fall armyworm and Striga.
Main threats
Recommended products
Cereals
Staple cereal of dry areas grown on light soils: pearl millet in the Sahel, finger millet in East Africa; early weeding, Striga and, in the Sahel, the millet head miner largely determine the harvest.
Main threats
Recommended products
Legumes
Early and late leaf spot, aphid-borne rosette and termites near harvest are the main threats; keep the crop weed-free until pegging.
Main threats
Recommended products
Legumes
Asian soybean rust, leaf spots and defoliating caterpillars are the main enemies; keep weeds under control until canopy closure.
Main threats
Recommended products
Oilseeds
Fast-growing export crop, highly sensitive to early weed competition, the sesame webworm (Antigastra catalaunalis) and leaf diseases.
Main threats
Recommended products
Fibre crops
Bollworms (Helicoverpa), jassids, aphids and whiteflies call for a planned protection programme from flowering to boll opening, with strict rotation of modes of action.
Main threats
Recommended products
Vegetables
Tuta absoluta, whiteflies (vectors of TYLCV), root-knot nematodes, late blight and early blight: only integrated protection with rotation of modes of action secures production.
Main threats
Recommended products
Vegetables
Diamondback moth (Plutella xylostella), quick to develop resistance, demands strict rotation of modes of action; also watch for aphids and black rot.
Main threats
Recommended products
Always read the label before use. Product information is given for guidance only; the label of the product authorised in your country always prevails.
