By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT Historically, research based on isolations on non-selective media suggested that black root rot caused by Thielaviopsis basicola was not an important component of the seedling disease complex on cotton in the Midsouth of the USA. Recent research with selective media or direct observation suggests that it is, in fact, a common problem in m...

Cotton Insect Pest Problems and Management Strategies in Côte d’Ivoire, W. Africa
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT The current pest management recommendations have become critical in Côte d’Ivoire. Variations in major pest profiles such as Polyphagotarsonemus latus (Banks) and Helicoverpa armigera (Hübner), show that calendar treatments do not always relate to field conditions or actual pest pressure. Furthermore, since the removal of insecticide subs...

Application Techniques to Meet the Requirements of IPM, IRM and Transgenics
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT Farmers continue to treat cotton with insecticides more than most other crops due to the wide range of insect pests that infest plants at different stages of their development. Excessive use of chemical control, especially with poor timing and inefficient application has led to major problems of insecticide resistance in several countries...

Proposed Strategies in Integrated Pest Management in the Gap Region of Turkey
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT Most of the cotton in Turkey has traditionally been produced in the Cukurova and Ege regions. However, increasing irrigation possibilities in Southeast Anatolia have enlarged cotton-producing areas in this region to equal those of Ege and Cukurova. It is suggested that after completion of GAP, an important irrigation project now under con...

Recent Advances in Cotton Production for Efficient Insect Pest Management
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT Insect pests sometimes cause a complete crop loss in India. Integrated pest management programmes world-wide emphasize the importance of agronomic practices but the bet options are seldom exercised. With the current scenario in India of pest management problems in cotton where none of the methods offer adequate control, it is felt increas...

Effect of Structural Adjustment Programmes on Pest Control in Tanzania:
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT Attack by Helicoverpa armigera remains the major constraint to increased productivity of cotton in Tanzania. For optimal yield, six preventive sprays of chemical insecticides are required during flowering for control of this pest. However, the abolition of subsidies on chemical insecticides/fertilizers and devaluation of the currency (bro...

The Israel Cotton IPM-IRM Strategy–Retrospect and Prospect
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT The Israeli IPM-IRM strategy, introduced in cotton in 1987, is focused primarily on controlling the whitefly, Bemisia tabaci. These and other cotton pests are controlled with novel insecticides and alternative control measures such as sex disruption against the pink bollworm (Pectinophora gossypiella), and by natural enemy encouragement....

Field Demonstration of Integrated Pest Management in Cotton in India
By Muhammad Naveed Arshad on Mar 6, 2019

Crop Protection WCRC WCRC2

ABSTRACT The traditional methods of insect control in India depended heavily on chemicals but results were often disappointing because of various factors, including pesticide resistance. Integrated Pest Management strategies have been devised to manage pests efficiently and economically with minimum environmental pollution. The measures include th...

Optimum Sample Size of Bollworms on Cotton Plants in Burkino Faso
By Muhammad Naveed Arshad on Mar 5, 2019

Crop Protection WCRC WCRC2

ABSTRACT Field experiments were conducted in cotton fields in 1997 in Burkina Faso, West Africa. Bollworms (Helicoverpa armigera, Earias insulana, E. biplaga, Diparopsis watersi) on cotton plants were sampled every week during the cotton growing season to assess the optimum sample size of bollworms in terms of the number of plants to randomly sele...

Spraying Apparatus for Pest Control in Cotton for the Small Farmer
By Muhammad Naveed Arshad on Mar 5, 2019

Crop Protection WCRC WCRC2

ABSTRACT It is expected that the small farmer will, in future, produce up to 30% of the seed cotton in South Africa. To achieve this, small producers will need to control insects cost-effectively with an apparatus that is affordable and acceptable to the farmer. An insecticide application apparatus for the small cotton farmer, based on a knapsack...

By Muhammad Naveed Arshad on Mar 5, 2019

Crop Protection WCRC WCRC2

ABSTRACT Cotton leaf worm (Alabama argillacea Hübner) is a migratory pest, a native of the tropics that moves into Argentina every year. Black light traps (15W BLB) were used to cotton leaf worm population fluctuation at Reconquista (Santa Fe, Argentina, 29º 11´LS and 59º 52´LO), two or three nights per week during 1981-1997. Adults were collected...

A New Technology for Improved Pesticide Coverage on Cotton Canopy. Part II: Field Efficacy
By Muhammad Naveed Arshad on Mar 5, 2019

Crop Protection WCRC WCRC2

ABSTRACT Whitefly (Bemisia argentifolii [Gennadius]), is widespread on cotton in hot, semi-arid areas. Apart from direct yield losses, the honeydew excreta causes stickiness of cotton fibers and enables sooty mould development. Whitefly is also a vector of a number of viral diseases. A major part of its life cycle is as a sessile larva on the unde...

Spatial and Probability Distribution of Aphis gossypii Infestation in West Africa: Application to Non Random Field Sampling
By Muhammad Naveed Arshad on Mar 5, 2019

Crop Protection WCRC WCRC2

ABSTRACT A non-random sampling plan is proposed for monitoring insect infestation in cotton to facilitate spraying, based on action thresholds, to control Aphis gossypii on cotton plants in Central Africa. Non random sampling is preferred to random sampling because it is easier to implement. It is validated by the spatial distribution of the insec...
