Selectives herbicides for cultivations

herbicide

The uncontrolled growth of the weeds causes the cultivations to fight against them to obtain the sunlight and the necessary nutrients, for this reason most of the time significant losses are generated. Since herbicides do not have the ability to differentiate between cultivation and weeds, conventional agricultural systems can only apply to selective herbicide cultivations. This type of herbicide does not affect the crop, however, it does not have a complete effectiveness to destroy all types of weeds. If farmers generate herbicide resistant crops, then it is possible to implement non-selective herbicides to destroy all weeds, quickly and efficiently with a single application. The result would be less spraying, less field traffic and lower operating costs.

 

Usefulness of non-selective herbicides

The herbicides of broad spectrum, commonly known as non-selective, have great effectiveness in destroying an extensive list of weeds. However, applying non-selective herbicides could destroy the crop. Therefore, non-selective herbicides are most useful when applied before seedling emergence or in unexpected cases in orchards, vineyards and nurseries.

Selectivity of herbicides

The reason why herbicides have a great value because they can be implemented just before planting or emergence of cultivations, they can even be used at the top after the emergence of the cultivation, without getting too many injuries. A large number of herbicides marked for this type of application, can currently selectively eliminate an extensive amount of weeds, without intervening with the crop. To achieve selectivity, two methods can be applied: placement selectivity and real selectivity.

 

Location selectivity

Achieving a selectivity by avoiding or decreasing the contact between the herbicide and the cultivation is known as location selectivity. The most common case is to direct an herbicide (such as: glyphosate) to a weed without exposing it to the crop

In an era of increasingly fierce competition, every time a company should evaluate its performance, as well as carry out a series of improvements, in order to continue to grow and be competitive.

One strategy to improve and maximize the performance of the company is by way of restructuring.
When we hear the term or word of restructuring, which there is our mind, as if talking about companies that are declining. This is caused by the definition of restructuring itself, are as follows:

Restructuring, often referred to as downsizing or layering, involves the reduction of the company in the field of labor, work unit or division, or a reduction in the level positions in the structure of the organization of the company. This enterprise-scale reduction is needed to improve the efficiency and effectiveness (David, F, 1997: 226)
The restructuring strategy is used to find a way out for companies that are not growing, illness or any threat to the organization, or industry on the threshold of significant change. The owners generally make changes in the team management unit, a change in strategy, or the introduction of new technologies in the enterprise. Furthermore, often followed by acquisitions to build a critical section, to sell unnecessary parts, in order to reduce the acquisition cost effectively. The result is a strong company, or an industrial transformation. The restructuring strategy requires a management team that has the insight to see into the future, when the company is at an undervalued or industry in a position ripe for transformation. The same insight necessary to make the turn around the business units, even on unfamiliar business (Mintzberg & Quinn,
