Other claims from this paper (12)

Intervention effect A single spring paclobutrazol application decreased shoot growth in tart cherry trees during the first and second seasons after treatment.
Intervention effect Paclobutrazol increased the proportion of flower buds to vegetative buds in tart cherry during the first dormant period.

Intervention effect Paclobutrazol tended to decrease rest intensity in both terminal and lateral buds of tart cherry.
Intervention effect In some tart cherry trees, paclobutrazol hastened the completion of rest.
Observation In tart cherry, lateral buds completed rest about one week before terminal buds regardless of treatment.
Observation Rest was completed in tart cherry buds at least by early December.
Intervention effect Flower buds from paclobutrazol-treated tart cherry trees had mid-winter T50 values about 2°C higher than controls.

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.

Other claims from this paper (7)

Intervention effect Nitrogen increased pasture yield, particularly at high stocking rates.
Intervention effect Nitrogen increased milk yield, particularly at high stocking rates.
Observation Mid-autumn to spring milk gains accounted for nearly all annual gains.

Intervention effect Cumulative fertilizer N recovery increased strongly when N uptake in unfertilized years was incorporated.
Intervention effect Cumulative fertilizer N recovery in N340 + DCD increased from 37 %–44 % in fertilized years to 74 %–80 % in unfertilized years.

Association At flowering, no relation between nitrogen and Akisengoku vegetative growth was recognized.
Intervention effect K-01 showed little or no growth response to nitrogen regardless of stage.
