Drip irrigation is popular among all people residing all over the world. The utility of drip irrigation is characterized by the presence of certain implied conditions to be satisfied. These technical requirements determine the overall activity of the drip irrigation system.

Technical requirements

The pressure is the main ingredient that is to be maintained by tubing with adequate level of supply of water. The tubing should withstand a pressure of about 2 bars. The tubing is to be maintained sufficiently deep in the ground. The ground can be dug to a depth that can be easily approached by the root tips of plants. Pressure regulation can be done to minimize or maximize the pressure that is maintained. Also flow valves can control the intensity of water. The ideal flow that is used is about 0.2l/s for standard dimension of tubing. The tubing that is generally employed in the drip irrigation is about 24mm diameter.

Pressure Regulator- Types

Pressure regulator is of different types. Varied range of pressure regulators can be used for the effective control of pressure in the tubing in different parts of the drip irrigation systems. They are numerous types and differ based on the design specifications namely—

  • Low flow pressure regulators

The design of low flow regulators is quite unique. Also the design can regulate pressure based on the utility. A flow rate of about 0.1 to 1GPM can be achieved with low flow pressure regulators.

  • Medium flow pressure regulators

Medium flow regulators are utilized for the gardens that require the flow rate of range 2- 20 GPM to be achieved. With this type of flow pressure regulators one can limit the pressure based on the inlet pressure applied.

  • High flow pressure regulators

Flow rate can be limited to about 32 GPM with this type of high flow pressure regulators. The external pressure can vary from 10 psi till 50 psi.

Greenhouse Pest Control

Greenhouses are gaining sufficient importance in the recent years. People are ready to adopt new techniques of plantation that tends to involve some amount of initial investments. As in any plantation, there are opportunities for the entry of pests. One needs to know more about the common pests that attack the plants that shelter under the greenhouses. The entry of pests in the ambient atmosphere within the greenhouses can lead to several other complications related to the growth of plants.

Greenhouse Pest Control

Greenhouse pest control involves the effective management of pest control techniques for elimination of the common greenhouse pests. Several techniques adopted in control of green house pests involve the use of sprays to control spread of pests. Certain insects involve use of soap preparations to wash off the green parts of the plant. Organic chemical scan also be sprayed to nullify certain pests.  Constant monitoring is required to make sufficient control measures for plants in green houses. Life cycle of certain pests is to be carefully monitored in order to plan for effective control methods. Development of the beneficial insects can be solution to tackle certain pests. The predators can be used to stop the attack of pests like aphids.

Common Greenhouse Pests

The common greenhouse pests involve aphids and scale inspects. The morphological features of the insects vary depending on the habitat that it survives. The common greenhouse pests like fungus gnats require presence of moisture around the plants, which encourages the growth and spread of fungus gnats. These tend to occupy the soil surface drying up all the organic matter present in soil. This greatly affects the growth of younger plants. Providing interrupted water supply can provide the pests inaccessible. Also the plant can be offered great defense by doing so. Sticky traps can be used to prevent the entry of some common greenhouse pests.
