Crop pests and diseases
Bacterial leaf spot and stem canker-this a bacterial infections affecting the leaves and the stem causing leafspots and cankers respectively. Best controlled by copper based fungicidal sprays. Use TRINITY GOLD 50G/20 LTS.
Halo blight-another bacterial infection causing blight on leaves. This are brown patches of dead tissue with an halo concentric ring round them. Control by TRINITY GOLD 50G/20LTS.
Alternaria blight-fungal infection leading to burnt leaf surfaces. Controlled by TRINITY GOLD 50G/20 lts.
Antracnose and cercospora leafspot-affects both leaves and pods. Best controlled by using TRINITY GOLD 50G/20 LTS.
Powdery mildew-fungal infection characterised by powdery white substance on leaf surface. Controlled by TRINITY GOLD 50G/20 LTS OR CHARIOT 20ML/20LTS.
POD BORERS-most important pest of pea with damage causing more than 80% yield loss. Larvae feed on pods flowers while adult bores into pods and seeds. Controlled by PENTAGON 10ML/20 LTS.
POD FLIES-white adults fly,lay eggs and developing maggots bore and feed inside the pods. Use PENTAGON 10ML/20 LTS OR PROFILE 440EC 30ML/20 LTS.
POD BUGS-both adults and nymph suck the plant sap from flower buds and developing seeds through the pod wall.Attached seeds are dark and inside become shrivelled. Best controlled by PENTAGON 10ML/20 LTS +INTEGRA 3ML/20LTS.
BLISTER BEETLES-also called flower feeders, they feed on flowers and reduce the number of pod setting hence affecting crop yield. Best controlled by PENTAGON 10ML/20 LTS OR LEXUS 8ML/20 LTS. INTEGRA sticker is necessary .
During vegetative and flowering phase, its necessary to spray Lavender total a complete foliar fertilizer to aid vegetation and tillering.
Application of optimizer is also necessary to enhance vigour, and flowering.
