Due to high temperatures and humidity, cotton, corn, vegetables and other crops are prone to insect pests, and the application of emamectin and abamectin has also reached its peak. Emamectin salts and abamectin are now common pharmaceuticals on the market. Everyone knows that they are biological agents and are related, but do you know how to choose between different control targets?

Abamectin is a very effective agent that can be used in almost all crops to prevent almost all pests, while Emamectin Benzoate is a similar agent with significantly higher activity than abamectin. The activity of Emamectin Benzoate is much higher than that of abamectin, and its insecticidal activity is 1 to 3 orders of magnitude higher than that of abamectin. It is extremely active against lepidopteran insect larvae and many other pests and mites. It has stomach poisoning effect and contact killing effect. It also has good insecticidal effect at very low dosage.
Because different pests have different living habits, the temperature at which pests occur is different. When using pesticides for control, the correct choice must be based on the living habits of the pests.
The occurrence of leaf roller is generally above 28~30℃, so the effect of Emamectin Benzoate in preventing leaf roller is much better than that of abamectin.
The occurrence of Spodoptera litura usually occurs during periods of high temperature and drought, that is, The effect
of Emamectin Benzoate is even better than that of abamectin.
The most suitable temperature for diamondback moth is around 22°C, which means that diamondback moth will occur in large numbers at this temperature. Therefore, Emamectin Benzoate is not as effective as abamectin in controlling diamondback moth.
Emamectin Benzoate
Applicable crops:
Emamectin Benzoate is highly safe for all crops in protected areas or at 10 times the recommended dosage, and has been used in many food crops and cash crops in Western countries.
Considering it is a rare green pesticide. Our country should first use it to control pests on cash crops such as tobacco, tea, cotton and all vegetable crops.
Control pests:
Emamectin Benzoate has unparalleled activity against many pests, especially against Lepidoptera and Diptera, such as red-banded leaf rollers, Spodoptera exigua, cotton bollworms, tobacco hornworms, diamondback armyworms, and beetroots. Moths, Spodoptera exigua, Spodoptera exigua, Cabbage Spodoptera exigua, Cabbage cabbage butterfly, cabbage stem borer, Cabbage striped borer, tomato hornworm, potato beetle, Mexican ladybird, etc
Abamectin
action and characteristics:
Contact poison, stomach poison, strong penetrating power. It is a macrolide disaccharide compound. It is a natural product isolated from soil microorganisms. It has contact and stomach poisoning effects on insects and mites, and has a weak fumigation effect, but has no systemic effect.
However, it has a strong penetrating effect on the leaves, can kill pests under the epidermis, and has a long residual effect. It does not kill eggs. Its mechanism of action is different from that of general pesticides in that it interferes with neurophysiological activities and stimulates the release of r-aminobutyric acid. R-aminobutyric acid has an inhibitory effect on the nerve conduction of arthropods, and mites, nymphs and insects interact with it. The larvae appear paralyzed after contact with the agent, become inactive and do not feed, and die after 2 to 4 days.
Because it does not cause rapid dehydration of insects, its lethal effect is slower. However, although it has a direct killing effect on predatory and parasitic natural enemies, it does little damage to beneficial insects because there are few residues on the plant surface. It has obvious effect on root-knot nematodes.
Control of pests:
Control of diamondback moth, cabbage caterpillar, diamondback moth, leafminer, leafminer, American leafminer, vegetable whitefly, beet armyworm, spider mites, gall mites, etc. on fruit trees, vegetables, grains and other crops. Tea yellow mites and various resistant aphids as well as vegetable root-knot nematodes.
