Practice Name:

Jassids in Cotton

Details
Category	Crop Production
Crop	Cotton
Crop Family	Malvaceae
Scientific Name	(Gossypium spp.)
Vernacular Name	Kapas
Scout	HBN
Ingredients	"kali veladi", water, spray pump
Details of Innovation	Many chemical pesticides have failed to control jassids in cotton (Gossypium hirsutum) crop. Because of its resistance development capacity against the chemical pesticides, it has become a hard task in controlling this pest. Generally jassid infestation is observed from 30 to 50 days after sowing in hybrid cotton and is not controlled by any bio pesticides even. To control this pest, three kilogram "kali veladi" is boiled in 20 L water, till it reduces to 5 L. Allow it to cool. About 100 to 150 g of the so prepared decoction is mixed in 15 L water in the spray pump and sprayed on the jassid infested cotton crop. This helps in controlling jassids in cotton crop. The method is cheaper and has no environmental hazards as compared to chemical control.

PAS_1	"Crop rotation is another cultural control measure widely adopted by most cotton farmers in Zimbabwe. Cotton is rotated with other crops in order to break the life cycle of pests and diseases. Crop rotation is effective on red and pink bollworms which have narrow host ranges. African and spiny bollworms are polyphagous, so will not be affected by rotations. Pink bollworm: While some insect pests are aggravated others are suppressed with rotations. The pink bollworm can only survive on cotton squares and bolls, thus large-scale rotation of cotton has a dramatic impact on this pest (Blasingane et al., 1991). Rotations crops used include maize, wheat and soyabeans." [Mapuranga, Rangarirai&Chapepa, B. &Mudada, Nhamo. (2015).

PAS_2	"Results of this study have shown that occurrence and abundance of cotton and cowpea pests is not affected by cotton and cowpea intercropping systems. Pesticides applied on cotton to control cotton pests in different intercropping arrangements significantly reduced populations of cowpea pests. This would therefore help famers reduce costs associated with pest’s management if cotton and cowpea were grown as intercrops as opposed to when each crop was grown as sole crop." [Kabambe, V.. (2016). Effects of intercropping systems and foliar pesticides applied to control cotton (Gossypiumhirsutum L) pests on incidences of cowpea (Vignaunguiculata L. Walp) pests. 6. 313-321.] https://www.researchgate.net/publication/318595362_Effects_of_intercropping_systems_and_foliar_pesticides_applied_to_control_cotton_Gossypium_hirsutum_L_pests_on_incidences_of_cowpea_Vigna_unguiculata_L_Walp_pests
