Physical and chemical properties, toxicities and model of action
Physical and chemical properties:
Appearance: yellow crystal, no special odor.
Melting point: 94.8 °C
Acute oral in rat: LD50>5000mg/kg
Acute dermal in rat: LD50>5000mg/kg
Mode of action: Insecticide Spirodiclofen has entirely new mechanism of action and kills mites by contacting, but no system mechanism. It mainly stops the fat synthesis of mites, blocking mites energy metabolism. It is effective on each growth stage of mites, including the eggs.
1. New structure and unique function mechanism
2. Broad spectrum, widely used
3. Killing eggs and young mites
4. Hold an effect in long period
5. Low toxic, low residue and safety
6. No mutual resistance
1. Evenly spray: The product has passed the prevention against the eggs, young female mites and adult mites by contacting. It has no system mechanism, Therefore,when adding water spray potion, ensure leaf sides and fruit surface are sprayed uniformly to maximize its efficacy.
2. The timing: As for prevention citrus MsGregor, suggesting use the product in its harm prophase in order to perform its long period characteristics.
(1) Regimen 1:
When red spider and yellow spider harm reach to control index (the eggs reaching up to 10 grains per leaf or the worm reaching up to 3-4 heads per leaf), using spirodiclofen24% EC diluted 4000-5000 times( 100ml/bottle is diluted with 400-500L water) to spay the plant uniformly. It can control the red spider and yellow spider for about 50 days. Henceforth, if the number of the red spider and yellow spider increase, just need to use the rapidly-available mites European -standard (such as pyridaben, gram mites and abamectin) for one more time.
If red spider and yellow spider happen earlier, using 1-2 times rapidly-available mites European -standard (such as pyridaben, gram mites and abamectin), in early may around, using the spirodiclofen 24% EC diluted 400-500 times (100ml/bottle is diluted with 4400-800L water) to spay the plant a time, it can control the red spider and yellow spider for about 50 days.
(3) The autumn regimen:
When the red spider and yellow spider population reach up to controlling index, use the mites European -standard diluted 4000-5000times to spray for one time or use mixing with other elixirs according to the situation. In this way, it can control the mites until the citrus harvest.
3. Applying times: It is better to use the mites European-standard just for one time during the citrus growth season and use rotational with other different mechanism Mites European –standard. Can effectively control resistance against mites and reduce the mite resistant to the risk of Mites European –standard.
1. The population is considerable high in the late-mid harm period. As for its good characteristics of killing mite eggs and young mites, it can be used with rapidly available and reasons short mites European–standard, such as abamectin. Can quickly kill the adult mites and control the recovery of the population of mites.
2. Considered the resistance management, use it in a growing season (spring and autumn), the limited using time is 2 times.
3. The way of the mites European-standard is by stomach toxicity and tagging. It has no systemic. So when you spray, spray the whole plant especially the back leaf.
4. Should avoid fruit trees booming when spraying it.
