Emamectin benzoate and Abamectin are common products we can find in the market. Everybody knows that they are bio-pesticides and they are relatives. But do you know how to make the choice for the different control targets?
Emamectin benzoate was developed from Abamectin and we can say it’s reinforced type Abamectin. They have similar pests killing spectrum.
Emamectin benzoate’s activity is 1-3 orders of magnitude than Abamectin. It has very high activity for the larvaes of the Lepidoptera pests, other pests and mites with both contact toxicity and stomach poisoning. Even at very low dosage, it can show a good efficiency.
But many documents show that their activity(especially the contact toxicity) will increase following with the rising temperature. However, the increasing range are different between them.
At 16℃, same content, Emamectin benzoate’s acticity is only 2-3 times than Abamectin; when the temperature rise from 16℃ to 22℃, the toxicity of Abamectin increases 6 times, but Emamectin Benzoate’s only rises 2-3 times. So from 16℃ to 22℃, their effect are nearly the same. But according to the present registrations, Abamectin’s A.I. Application qty/ha is higher than Emamectin Benzoate. So in the actual applications, the application qty of Abamectin is higher than Emamectin Benzoate and the effect of Abamectin is also better from 16℃ to 22℃.
However, when the temperature is higher than 25℃, Emamectin Benzoate’s toxicity can increase up to 1000 times, but Abamectin’s can only increase no more than 20 times. So we can see a lot better efficiency of Emamectin Benzoate than Abamectin.
Because different pests have different habits and the damage occurring time is also different. So we have to make the right choice according to their habits.

Because different pests have different habits and the damage occurring time is also different. So we have to make the right choice according to their habits.
For example, usually leaf-roller’s damage begins when temperature is higher than 28-30℃, so we can choose Emamectin Benzoate. Spodoptera litura’s damage usually occurs from July to October and the temperature is also higher than 28-30℃, so we should also choose Emamectin Benzoate. But the Dimond back moth’s damage usually occurs at 22℃, so sometimes farmers may not get satisfied control result if choose Emamectin Benzoate, not Abamectin.
