BON RIZ 400 SC: post-emergence weed control in rice

Based on bispyribac-sodium, BON RIZ 400 SC controls barnyard grass, sedges and broadleaf weeds in direct-seeded and transplanted rice, at a very low rate per hectare.

Weeds that emerge with the crop cause the heaviest losses in rice. BON RIZ 400 SC is sprayed on young weeds, 10–25 days after sowing or transplanting; the field is drained for the treatment and re-flooded a few days later.

Use clean water, spray evenly and alternate with herbicides that work in a different way, such as BON PROPLUS 560 EC, to keep resistant weeds in check.

BON RIZ 400 SC is available in 200 mL bottles from our network in Ghana. Always read the label before use.

Field days on safe use and sprayer calibration

BonAgro Ghana offers practical sessions for farmer-based organisations and input dealers on safe handling, sprayer calibration and empty container management.

Accurate spraying protects the crop, the operator and the environment. Our field sessions cover reading the label, choosing and wearing protective equipment, calibrating a knapsack sprayer and preparing the spray mix correctly.

Participants also practise triple rinsing and learn how to store products safely at home and in shops, away from children, food and animal feed.

Farmer-based organisations and input dealers who would like to host a session can contact us through the online form, giving their location and main crops.

Cocoa black pod season: start copper sprays on time

Black pod disease spreads quickly in the rainy season. Preventive copper sprays, together with regular removal of infected pods, protect the developing crop.

Black pod, caused by Phytophthora species, thrives when pods stay wet. Spores are splashed by rain from infected pods, the soil and tree bark onto healthy pods.

Combine sanitation — removing and disposing of black pods at every visit — with preventive fungicide sprays at the intervals given on the label throughout the risk period. Good shade management and pruning improve air movement and help pods dry faster.

Use only fungicides recommended for cocoa, and follow the label for rate, interval and protective equipment. Our advisers can help you plan the programme for your farm.

Fall armyworm in maize: scout early, act at the right stage

Fall armyworm damage is most serious on young maize. Regular scouting helps you spot infestations while larvae are small and easiest to control.

Young larvae feed inside the whorl, leaving translucent windows on the leaves, then ragged holes and sawdust-like frass. Scout fields twice a week from emergence, checking plants in several parts of the field.

When fresh damage reaches the action threshold recommended by extension services, spray early in the morning or late in the afternoon, directing the spray into the whorl. Emamectin benzoate, the active ingredient of AWAY 1.9% EC, acts on caterpillars feeding on treated leaves.

Rotate insecticide groups between sprays and seasons, and combine chemical control with good practices such as timely planting and the destruction of crop residues.

Major season: clean land preparation with glyphosate

Controlling weeds before planting gives your maize, rice or vegetables a clean start. Timing, water quality and the right nozzle make all the difference.

Glyphosate works on actively growing green weeds, moving from the leaves down to the roots and rhizomes. Spray after the first rains, once weeds have regrown, rather than on dry or freshly slashed vegetation.

Use clean water — muddy water reduces efficacy — and a flat-fan nozzle at steady pressure. Respect the rain-free period on the label and wait for the weeds to die back before planting, as recommended.

KING KONG 480 SL and BONSATE 480 SL are available from our distribution network in Ghana for pre-plant land clearing and directed inter-row weed control in plantation crops. Always read the label before use.

Dry-season tomato: managing nematodes and Tuta absoluta

Irrigated tomato in the north faces two major threats: root-knot nematodes in the soil and the tomato leaf miner on the foliage. Plan protection from the nursery stage.

Root-knot nematodes form galls on the roots, reducing water and nutrient uptake. Plants wilt in the heat of the day and yields fall. Fields cropped with tomato, pepper or other susceptible vegetables season after season are most at risk.

Start with a healthy nursery, rotate with non-host crops such as cereals, and avoid tomato in fields where galls were seen the season before. For Tuta absoluta, use pheromone traps to detect the pest early, remove infested leaves and fruits, and alternate effective insecticide groups.

Emamectin benzoate, the active ingredient of AWAY 1.9% EC, reaches the larvae inside their leaf mines. Our outlets in Tamale and Bolgatanga can advise on application timing.

Always read the label before use. Product information is given for guidance only; the label of the product authorised in your country always prevails.
