Control of the variegated grasshopper Zonocerus variegatus (L.) on cassava

W. W. D. Modder TSpace 1994

Other claims from this paper (10)

Observation Early instars aggregate off farm, while later instars and adults move to crops when food becomes scarce.
Mechanism Aggregated feeding by larger grasshopper instars causes cassava leaves to wilt and lose HCN quickly.
Recommendation Eradication of Chromolaena odorata probably will not control the grasshopper.
Observation Chemical control is described as only short term effective and environmentally damaging.
Intervention effect Chemical sprays against the grasshopper kill parasitoids introduced for cassava mealybug control.
Intervention effect Exposing egg pods at the soil surface produced large grasshopper population reductions.
Intervention effect Fungal spores in kerosene and peanut oil killed 70-95% of field grasshopper populations.
Intervention effect A strain isolated from the grasshopper caused 90% mortality in 7-9 days in the laboratory.
Intervention effect Grasshoppers leaving spore baited traps died within 10 days, up to 30 m away.
Intervention effect Additional defoliations decreased cassava root yield.

The epidemiology of tomato brown root rot

F. T. LAST; MARION H. EBBEN Annals of Applied Biology 1966. doi:10.1111/j.1744-7348.1966.tb06870.x

Other claims from this paper (19)

Observation Three brown root rot symptoms occurred on tomato roots in infested soil without nematodes.
Observation Brown lesions appeared within a week of planting in heavily infested soils.
Observation Corkiness and black dot rarely appeared until the third month after planting.
Observation Black dot incidence sometimes rose sharply toward season end.
Association Observations suggested GSF caused more damage than C. atramentarium.
Association Yield was unrelated to black dot incidence.
Association Yield was inversely proportional to brown lesion occurrence.
Association Yield was inversely proportional to corkiness occurrence.
Association The yield relation with brown lesions was significant within eight weeks of planting.
Observation Early brown lesions mostly yielded GSF cultures, whereas later lesions more often yielded C. atramentarium.
Intervention effect Most GSF cultures produced 10 mm brown lesions on tomato seedling roots within two weeks.
Intervention effect C. atramentarium inoculation produced small pink lesions.
Intervention effect Pyrenochaeta inoculation produced no lesions.
Intervention effect GSF caused greater root damage, including root loss, in soil tests.
Association GSF root damage was reflected in decreased aerial growth.
Association GSF root damage was reflected in smaller fruit yields.
Intervention effect C. atramentarium did not affect aerial growth or fruit yield in soil tests.
Intervention effect In the second year, GSF lowered six week picking yield from 1.96 kg in controls to 1.02 kg per plant.
Observation GSF damage shifted with plant age: brown lesions appeared within days, while corkiness appeared after two to three months with stem lesions and yellow leaves.

SINGH H.G; SAROHA M.S; SHAKTAWAT M.S Madras Agricultural Journal 1977. doi:10.29321/maj.10.a03155

Other claims from this paper (7)

Recommendation At most 100 per cent replenishment of nitrogen removed by weeds was needed to reduce competition.
Intervention effect Increasing simazino rates significantly increased maize yield.
Recommendation Half a kilogram of pre-emergence simazine was judged the best option without harmful wheat residual effects.
Recommendation Pre- and post-emergence 2,4-D at 0.5 kg/ha with full weed nitrogen replenishment was the most beneficial treatment.
Intervention effect Simazine at half a kg/ha increased maize yield by 4.2 g/ha.
Intervention effect Simazine at half a kg/ha reduced weed dry matter production by 13.2 g/ha.
Intervention effect Simazine at half a kg/ha had no harmful effect on wheat.
