It fetches excessive costs available in the market and is wealthy in nutritional vitamins and fats, amongst different vitamins. Nonetheless, rising the crop comes with a number of challenges that make farmers harvest losses.
Seeds of Gold visited a sunflower farmer not too long ago and one of many issues we seen concerning the crops on one block of his farm is that some had been yellowing whereas others had white substances on the leaves.
Seeds of Gold talked to Dr Moses Biruma the programme chief on the Nationwide Semi Arid Assets Analysis Institute (NaSARRI) about illness administration.
Built-in pest administration
Built-in pest administration (IPM) is a sustainable strategy to managing pests by combining organic, cultural, bodily and chemical instruments to reduce financial, well being and environmental dangers.
IPM maximises the effectiveness of chemical pesticides, whereas minimizing the impression on non-target organisms and the atmosphere. The pests and illnesses differ as a result of some infest the leaves, the roots and the top as described beneath.
Wireworm larvae feed on germinating seeds or younger seedlings. Infestations usually tend to develop the place grasses, notably perennial grasses, have been rising. Stems of younger seedlings might emerge shredded. This results in wilting and demise of the plant.
Cutworms generally is a major problem in lots of discipline crops. The commonest are the crimson backed, darkish sided and dingy cutworms. The crimson backed cutworm majorly feed on greens and kitchen backyard vegetation together with spices.
Feeding by grownup beetles and larva might lead to poor seed set, seed filling, diminished yields and delayed maturity. Sunflower beetles feed on native and cultivated sunflowers. They often emerge from the soil.
Sunflower bud moth
Excessive populations of this pest have been reported up to now. Regardless of excessive populations, the sunflower bud moth might not trigger excessive ranges of financial loss. Many of the infestations happen within the stalks and pith areas of the top. The one time yield loss is noticeable is when larvae burrow into unopened buds, stopping correct head growth.
They’re of various species which have larval feeding phases that may trigger seed sterility or stalk breakage below excessive populations. Injury is often negligible.
Sunflower seeds are notably weak to predation by blackbirds as a result of excessive dietary worth, simple accessibility and heads serving as a perch throughout feeding.
Blackbird nests are inbuilt dense vegetation, most frequently.
“To manage some illnesses particularly throughout wet seasons, a farmer ought to have correct drainage on the farm, which will be achieved by creating channels that permit extra water to empty out,” says Dr Moses Biruma.
