Importance of Cotton Source of income for more than 300.000 families in the country, One of the main agricultural export products, Employs many people through out the season, Cultivated under concessionary system, in small scale farming Low productivity associated with inadequate cultural practices, incidence of pests, The crop that uses more pesticides in the country, IPM program started to be developed in 2005. I
BCI production principles: Better Cotton is produced by farmers who minimise the harmful impact of crop protection practices) IPM By farmers who use water efficiently and care for the availability of water By farmers who care for the health of the soil By farmers who conserve natural habitats By farmers who care for and preserve the quality of the fibre By farmers who promote decent work
Important Cotton Pests in Mozambique
Important Cotton Pests in Mozambique Divided in 3 groups Early sucking pests Chewing pests Late sucking pests Intermediary sucking pests
1. Early sucking pests 1. Jassids 2. Aphids
Jassids (sucking pests) Empoasca fascialis (Hemiptera: Cicadellidae) Inject toxins in plants, disturbing the synthesis of sugars Polifagous Life cycle 3-4 weeks
Aphids (sucking pest) Aphis gossypii Hosts (citrus, vegetable crops, etc) Short life cycle
Intermediary sucking pests Mealy bug Spider mites Phenacoccus solenopsis
Spider mites Tetranychus spp.
2. Chewing pests (caterpillars and grasshoppers) 1. American bollworm 2. Red bollworm 3. Pink bollworm 4. Other caterpillars
American bollworm Helicoverpa armigera Polifagous Feed on cotton bolls, flowers and leaves Many bolls per day Natural enemies important in control Ex: Trichogramma e Telemonus LE 6 eggs or larvae/24 plants
Red Bollworm Diparopsis castanea Found only in Africa Found only in cotton Feeds inside the flowers and cotton bolls 3 arrows on a V shape on the back Pupate in the soil NE important in control ex. Trichogramma and ants Pheidole LE 6 eggs or Larvae /24 Plants
Pink bollworm Pectinophora gossypiela Feeds inside flowers and cotton bolls Cutting and burning plant remains for control LE = 6 eggs or 6 larvae per 24 plants
Lagarta espinhosa Earias biplaga e Earias insulana Brownish in color Adult is green Break plant tips, feed on flowers and cotton bolls Cutting and burning plant remains LE = 6 eggs or 6 larvae in 24 plants
Spodoptera spp. Others: Leaf feeders
Grasshopers
3. Late sucking pests (cotton stainers) 1. Dysdercus spp.
Cotton stainer Dysdercus spp. Nymphs are reddish Adults black/reddish and brown Found in colonies Damage Feed on young capsula excrements stain cotton fiber LE = 6 colonies in 24 plants
(Integrated Pest Management - IPM) What is IPM? Combination of various methods that are economically, environmentally and socially viable / acceptable Involve scouting for monitoring pest population

Chemical control Last resort if strictly necessary (LED). Chose: Low toxicity Low persistence Specific Low cost
Resistent varieties
Trap cropping / strip intercroping 1. 12 rows of cotton followed by 4 rows of other crops (maize, pigeon pea) 1. Enhance conservation of beneficials 2. Crop rotation 1. Sequence: cotton, leguminous crops, cereals, cotton.

Exchanging experiences on IPM with Indian experts Title. Partnership between BCI, IAM and SOLIDARIDAD secures experience exchange between Mozambique and India on better cotton production. Through the partnership between IAM (The National Cotton Institute of Mozambique), BCI (Better Cotton Initiative) and SOLIDARIDA, Dr. Selvam Neeravi, an Entomology and IPM expert from the Solidaridad Cotton Network in India was brought to Mozambique to train the cotton sector national trainers. The training took place in Namialo Nampula from 7 to 18 th August 2013, and had 45 participants coming from IAM, Cotton Concessions, Input providing companies and other cotton stakeholders. Besides training and interacting with the trainers, who were very pleased to be exposed to the Indian experience and share the Mozambican experiences, Dr. Selvam had a second section of training with 64 extensionists of the extension network in OLAM-Ribaue, in which the main topics discussed were the integrated crop management, with emphasis on the use of locally available strategies of pests, diseases and weeds control
