Description
Technical field
The present invention relates to the miticide composition that formed by effective active components spiral shell mite ester and Hexythiazox, belong to technical field of compounded pesticide.
Background technology
Spiral shell mite ester, English name Spirodiclofen has the brand-new mechanism of action, and the tool action of contace poison does not have interior absorption.The main Fatty synthesis that suppresses mite, the energy metabolism of blocking-up mite, each developmental stage of mite is all effective, comprises ovum.
1. brand new, the mechanism of action are unique: the effective ingredient of spiral shell mite ester is spirodiclofen, and mechanism of action is the Fatty synthesis that suppresses in the pest mite body.Without cross resistance, be applicable to prevent and treat the pest mite class that existing miticide is produced resistance between it and existing miticide.
2. kill that mite spectrum is wide, strong adaptability: spiral shell mite ester all has fine preventive effect to two spotted spider mite, yellow spider, Xiu Pi lice, yellow tea mite, Tetranychus cinnabarinus and Tetranychus urticae etc., and the mite evil that can be used for the solanaceous crops such as the fruit tree such as citrus, grape and eggplant, capsicum, tomato is administered.In addition, spiral shell mite ester has the well double effect of controlling to insects such as pear sucker, oystershell scale and leafhopper classes.
3. double the killing of ovum children: the ovicidal effect is excellent especially, if simultaneously the children mite is also had good action of contace poison.Although spiral shell mite ester can not kill female one-tenth mite quickly, female one-tenth mite there is good sterilisation-effect.Female one-tenth mite touches the ovum that produces after medicine has 96% can not hatch, and dies from late embryogenesis.
4. the lasting period is long: the lasting period of spiral shell mite ester is long, can control citrus red mite (crm) harm in production and reach 40 ~ 50 days.Resistance of rainwater washing against after spiral shell mite ester is executed on crop leaf, the spray medicine is met the normal performance that moderate rain does not affect drug effect after 2 hours.
5. low toxicity, low-residual, safety are good.Very safe to crop under different temperature conditions, to people and animals and crop safety, low toxicity.Be suitable for nuisanceless production.
6. without transreactance: can use with existing the mixing now of most of agricultural chemicals (except strong basicity agricultural chemicals and copper agent).Mixed with existing miticide, both can improve the quick-acting of spiral shell mite ester, be conducive to again the resistance management of mite evil.
Hexythiazox, English name hexythiazox, invalid to the one-tenth mite if various plants is done harm to the characteristic that mite has strong ovicidal, kills the children mite, but the ovum that the female adult that touches liquid produces is had the effect that suppresses hatching.Good to the tetranychid preventive effect, relatively poor to rust mite, goitre mite preventive effect.Can be mixed with Multiple Pesticides such as bordeaux mixture, lime sulfurs.Take action of contace poison as main, plant tissue there is good permeability, without interior absorption effect.Control panonychus ulmi, Tetranychus urticae two spotted spider mite are if contain the children mite phase of sending out.
In China's agricultural production real process, chemical control is the main effective means of control mite class.The problem that the chemical control insect the most easily produces is the generation of pest resistance to insecticide.The mite class easily develops immunity to drugs, panonychus citri especially, and under the environmental condition of long-term prescription, resistance increases obviously.Be mainly used in preventing and treating the medicaments such as mite class medicament such as pyridaben, azacyclotin, Hexythiazox, clofentezine and use separately the harm of uncontrollable mite class.
For the mite pest that produces resistance on agricultural, a kind of way is to release new and the new component of existing product without cross resistance.But the development cost of new active ingredient is high, and the construction cycle is long, and forever all produces the speed of resistance less than insect.Other method such as crop allocation adjustment, biological control etc. in actual mechanical process, are difficult to really play a significant role.
, be difficult to obtain because spiral shell mite ester single dose needs import in China, and expensive, the preparation that it is made uses and is confined to the part developed area, can not use for all have the peasant in the area that needs.Due to resistance problem, other cheap miticide effect commonly used is poor again.Therefore control efficiency is good, the relatively low complex miticide agent of use cost is the demand that vast farmers is thirsted for most, adopts composite miticide composition to be expected to improve miticidal effect, reduces the agricultural chemicals usage amount, reduce costs, become the effective means of the various diseases of integrated control.
