Brazil is one of the countries with the greatest agricultural potential in the world, presenting high production of grains, vegetables and fruits. This is possible because the territory has continental dimensions, with great availability of water, favorable climate, agricultural technology and leading research, all in favor of Brazilian production.
However, an FAO estimate has indicated that between 20 and 40% of global crop yields are simply lost due to pest and fungal damage. In Brazil, the book "Plant Defense - Fundamentals, Tools, Policies and Prospects" indicates that the loss can exceed R $ 55 billion / year.
Faced with this reality, the country needs to consider a more effective pest and fungus control, to the point of reducing damages to the crop and, consequently, to the business as a whole. We already talked about the blog about the posture of the rural producer to protect his crop, remember?
But how to carry out pest and fungus control in the field in a more effective way so that the financial loss is reduced? This is what we will discuss in this post. Follow it.
However, by following this timetable, the producer tends to apply the chemical at an inappropriate time and in excess with a compound that is not compatible with the need, which results in a greater environmental impact and, of course, required.
Solution: integrated pest management
To reduce these negative effects, the farmer must adopt what we call integrated pest management (IPM).
IPM is a multiple pest control strategy, based on ecological control and natural mortality factors. IPM seeks to develop control tactics that interfere minimally with the purpose of reducing the chances of insects or diseases to adapt to some particular defensive practice.
Thus, when well used, the control of pests and fungi through the IPM technique has several advantages, since it limits the potential harmful effects of chemical pesticides in agriculture, public health and the natural environment, since it does not reduce the population of natural predators.
Hence the importance of performing the correct monitoring of the crop, from planning to harvesting. This is what we will discuss next.
Basically, the efficient monitoring of the crop should be done with 3 purposes:
· Detect a new species;
· Measure the level of infestation through population dynamics;
· Identify when and where a particular pest is present.
This practice also measures the possible damages and losses that may occur in the field. Finally, monitoring will be fundamental in defining the application of combat measures, in the case of insecticides, fungicides, or biological control.
Monitoring should be started at the planning stage of the crop, that is, before planting, and follow the entire development of the crop. For this, the producer needs to consider climate, humidity, temperature, time, in addition to the variety of planted culture.
It is also crucial to correctly identify the most recurrent pests and fungi in the region in order to guard against undesirable future "visits." For this, the use of technology is essential.
