Application-pesticidesAlready some readers of the Gate of Agriculture are sharing and asking how the technique of mixing the right pesticide. That's why maspary wants to write this article. Actually this article is a continuation of our previous writing about How to Appropriate Pesticides Applications.
Indeed there are no guidelines or guides that provide insight into how to properly mix pesticides. Therefore there are still many farmers who do the mixing of pesticides indiscriminately but there are also farmers who do not dare to mix pesticides at all for fear that mixed pesticides will react unfavorable to the plant. Therefore maspary ventured to give a little tips how to mix the right pesticide techniques.
Maspary dare to write this article not based on the reference of a book but only based on our experience in the field some time ago when we served in Dieng Kab. Wonosobo.
According to maspary there are several things to note in the proper mixing techniques of pesticides:
Do not mix pesticides directly in the sprayer tank (this is often the maspary encounter in the field), you should do the mixing of pesticides in plastic containers first (bucket). Once mixed in a new bucket insert inside the sprayer tank.
Do not mix pesticides directly in cans / packaging without diluting them first with water. (This event is also often metpary encounter on farmers who want to be practical, or sometimes keep secret the use of pestisidanya)
Do not mix 2 pesticides or more in one class, for example: Synthetic pyrethroid with synthetic pyrethroid or carbamate with carbamate.
Do not mix 2 pesticides or more that have a cooperative way, for example: respiratory toxins with respiratory toxins, systemic contact or systemic contact.
If you want to mix pesticides should do mixing pesticides that are in contact with pesticides that are systemic. If you want to control the disease in a plant and forced to mix the fungicidanya select the contact and the systemic. Contact fungicides are usually broad-spectrum and are usually protective or protective only because these fungicides are multisite inhibitors whereas systemic fungicides are usually narrow and eradicative or treating because these fungicides have a monosite inhibitor.
Sort mix pesticides according to their formulations. According to the experience of maspary in the mixing of pesticides start with a pesticide formulated WDG, WP or other flour-shaped mix until dissolved. The second just enter the PPC or leaf fertilizer if using a leaf fertilizer and stir it until mixed. The third step enter the pesticide formulated SL, WSC, SC etc and stir until dissolved. Fourth, enter the pesticide formulated by EC and lastly enter the adhesive, the smoothing, the penetrate etc.
Attention!! After you mix the pesticides like the order no 5 above there are other things to note. Do not use a mixture of pesticides whose solution is clot and / or settles. Based on the experience of maspary usually a mixture of pesticides that precipitate or agglomerate if applied to the plant will be able to damage the plant or sometimes does not work at all.
There are additional tips from the maspary that the readers of all Agricultural Gateway readers need to know is that mixing synthetic pyrethroid insecticides with organophosphate group insecticides will increase their efficacy, like 1 + 1 = 3. But do not mix insecticides group of organophosphates with carbamate because it will decrease its efficacy (1 + 1 = 1).
Hopefully with writing from the Gate of Agriculture this can provide benefits for readers of all who will apply pesticides and can provide a little enlightenment for those who are confused to mix pesticides. And hope of the Agricultural Gate hopefully this article can contribute to the success of farming for Indonesian farmers. (Maspary)
