Plant protection chemicals include chemical materials and their formulations protecting the plants and agricultural crops from all kinds of diseases, pests and weeds. If plant protection chemicals are not used in agricultural protection today, the crop yield results in a loss of nearly %65. For this reason, it is highly important for farmers to know the plant protection chemicals well, and have enough information about the applications, mixing and storing techniques of these chemicals.
Plant protection chemicals can be classified in various ways;
As per physical conditions:
They can be classified into two groups as;
- Solid Formulations
- Liquid Formulations
In accordance with the formulation type, solid formulations can be classified as:
- Powder formulations
- Dry seed treating formulations,
- Qettable powder formulations
- Granule formulations
In accordance with the formulation type, liquid formulations can be classified as:
- Emulsifiable formulations
- Aolutions and liquid dips
- Aummer oil and winter oil
- Flowable concentrate or suspension concentrate formulations
- Liquid formulations that can be used without being diluted
Although it seems easy to prepare the chemicals for application, the process can affect the success of the application if necessary care is not given.
While preparing the solid formulations for application, the procedure is as follows;
Bin of the spraying tool is filled with the water at the rate of 1/3 (three for one). Chemical in an enough amount is put to a clean tin, bucket or to a plastic container. Some water is added to the chemical and this mixture is emulsified through stirring with a clean stick. With this process, the whole of the chemical particles are damped with water. After that step, the water is added to the emulsion with constant stirring. This process goes on till the water level reaches up to the middle level of the container. This mixture is immediately added to the water inside the bin of the tool. Then, while stirring the emulsion, the water is added till the water level reaches up to the top level of the bin.
While preparing the liquid formulations for application, the procedure is as follows;
Bin of the spraying tool is filled with the water in the rate of 1/3 (three for one). Water in an amount of half of the container is added to a clean tin, bucket or to a plastic container. Liquid chemicals in an enough amount is added to this water. By stirring this emulsion, a mixture is obtained. The following procedure is similar with the one in solid formulations. The prepared chemical mixtures should be applied immediately.
It is dangerous to take a break for eating, smoking or resting, because some deterioration can be seen in chemical as per the pH and toughness of the used water. If there are two living factors harmful for the plant, it will be both time-efficient and cost efficient to use the chemicals together by mixing them instead of using them seperately. However it is important to be careful by choosing the chemicals to be mixed with each other should have same formulation type generally.
Consult agricultural organizations if needed
The first thing to do while choosing the chemicals is reading the labels of the chemicals. One can find some information about the mixing cases of the chemicals with other chemicals on the labels. If the label information is not enough, the information can be got from chemical mixture schemes. If there is not enough information on chemical mixture schemes, it will be useful to consult agricultural organizations.
