What is a push-pull system in agriculture?
The push-pull strategy for cereal stemborers involves trapping stemborers on highly attractant trap plants (pull) while driving them away from the main crop using repellent intercrops (push).
How does push-pull technology improve plant productivity?
Soils : Push–pull technology improves soil health through nitrogen fixation (desmodium being an efficient legume for this), increased soil organic matter content, conservation of soil moisture and reduced soil temperatures.
What are push and pull stimuli?
Push-pull strategies involve the behavioral manipulation of insect pests and their natural enemies via the integration of stimuli that act to make the protected resource unattractive or unsuitable to the pests (push) while luring them toward an attractive source (pull) from where the pests are subsequently removed.
Where is push pull technology used?
Cereals, which include maize, sorghum, millet and rice, are the main staple and cash crops for millions of small-scale farmers in most of sub Saharan Africa (SSA).
How does the push pull system prevent soil erosion?
crop/livestock production system It harnesses complex chemical interactions that destroy stem borer larvae and inhibit the growth of Striga weed. The system provides year-round soil cover, helps conserve soil moisture and soil structure, and prevents erosion.
Who are the authors of push pull technology?
Push-pull technology (www.push-pull.net) is based on a novel cropping system developed by the International Centre of Insect Physiology and Ecology, Rothamsted Research (UK) and national partners for integrated pest, weed and soil management in cereal-livestock farming systems.
What is the difference between push and pull technology?
Pull technology is used anytime the transfer of information is initiated by a request sent from a client to a server. Push technology, on the other hand, is implemented any time a transfer of information is initiated by a server without waiting on a request from a client.
What is push pull in IPM?
‘Push-pull’ is the first IPM strategy that effectively controls both stemborers and striga weeds, while ecologically improving soil fertility. The technology increases maize yields by protecting the crop against attack by the stemborer moths, Busseola fusca and Chilo partellus.
What is meant by push pull train?
The push- pull operation of locomotive is a configuration for locomotive-hauled trains, allowing them to be driven from either end. In this mode, one locomotive each is attached to the train at both ends. The train is then pulled and pushed by the locomotives simultaneously.
What is an example of pull technology?
Downloading Web pages via a Web browser is an example of pull technology. Getting mail is also pull technology if the user initiates a request to retrieve it.
Which is an example of push technology?
Common examples of push services include synchronous conferencing, email and instant messaging. Both centralized and decentralized programs permit file pushing. There are two major advantages to push technology: It is an instant service for transmitting information.
What is the push pull farming strategy?
The strategy involves combined use of intercrops and trap crops, using plants that are appropriate to the farmers. This push-pull strategy does not use any chemical deterrents or toxins, but uses repellent plants to deter the pest from the main crop.
What is push-pull technology in agriculture?
Push–pull technology is a strategy for controlling agricultural pests by using repellent “push” plants and trap “pull” plants. For example, cereal crops like maize or sorghum are often infested by stem borers. Grasses planted around the perimeter of the crop attract and trap the pests,…
What is the push-pull strategy for controlling striga?
The push- pull strategy provides significant suppression of striga through intercropping maize or sorghum with desmodium, a repellent plant for stemborers.
What is the push-pull strategy for cereal stemborers?
The push-pull strategy for cereal stemborers involves trapping stemborers on highly attractant trap plants (pull) while driving them away from the main crop using repellent intercrops (push).
