Pests and insects.. Many greenhouse owners and farmers may suffer from the spread of insects and agricultural pests, but they cannot determine the appropriate and correct ways to get rid of them. In fact, the methods and methods of pest control in greenhouses are as diverse as those pests, and in this article We will focus on one of the most effective control methods in this regard, which is chemical control..
Agricultural pests and insects
- Pests are any species or race, whether of plants or animals, that cause harmful disease to agricultural crops.
- Recently, many types of transboundary insects have spread, as a natural result of trade, climate change, globalization… and other factors.
- The fact is that these different types of pests and insects represent a major threat to global food security; Because it destroys not a small amount of crops.

How to use chemical control
As we mentioned earlier, there are many methods that greenhouse farmers can use to get rid of agricultural pests, but chemical control methods remain among the most effective, fastest and most widespread methods.
Chemical control includes 3 basic elements:
Using specialized pesticides
- One of the elements that must be taken into account when using chemical control of agricultural pests is to rely on specialized pesticides, in order to avoid any negative effects on beneficial organisms.
- Specialized chemical pesticides also help to maximize the degree of focused effect on agricultural pests.
- On the other hand, the use of agricultural pesticides that harm beneficial organisms is a big risk, as they usually cause an imbalance in the ecological balance inside the greenhouse.
- For example, using Methomyl to get rid of the tunnel makers bug will eliminate both harmful and beneficial insects.
Using selective spraying to control pests and insects
- Due to the small area of greenhouses compared to open fields, spraying is often used to distribute chemical pesticides on crops.
- Manual spraying is a more hygienic method than spraying with high pressure motors.
- The use of these motors leads to the loss of a large amount of spray solution, ranging between 70:90%.
- An alternative to selective spraying is the use of mist spray, which also reduces the amounts of pesticide lost, and also contributes to delivering the pesticide to hard-to-reach places through regular sprayers.
Choose the appropriate timing for the spraying process
- Among the factors that affect the efficiency of pesticide spraying; That the farmer be able to determine and choose the appropriate timing for it.
- Choosing the right timing protects plants from any allergies or damage at any stage of their growth.
- For example, when you see an insect that creates tunnels as well as tunnels, it is preferable to spray only locally in order to infect, but if the insect feeding spots are present completely; It is recommended to postpone the spraying process for two or three days in order to ensure that the eggs hatch.
It remains to point out that there are a set of instructions that may avoid the need for agricultural pesticides, and contribute to limiting the spread of insects and pests inside your protected house.. This includes choosing a suitable site for the house that is not adjacent to open plants where insects abound, and maintaining humidity levels. Reasonable, and the greenhouse must be kept away from any tall trees that may shade and block the sun from it, so as not to increase the possibility of insect infestation.
