Description
Technical field
The present invention relates to a kind of microcapsule suspending agent, especially a kind of microcapsule suspending agent containing biostimulant and its preventing and treating
The application of crops nematode, belongs to technical field of pesticide.
Background technology
World wide implants nematode causes 157,000,000,000 dollars of losses every year.Only China's root knot nematode year occurring area
More than 20,000,000 mu, banana is every year because of nematode loss 20%.Nematodiasis has gone up the disease for being most difficult to administer for veterinary antibiotics and asked
One of topic.
Currently, nematode is still based on chemical prevention, and a large amount of chemical pesticides are protruded using the problems such as causing environment and residual.Cause
This, the control of nematode medicament of exploitation more environment-friendly high-efficiency turns into the task of top priority.With technological progress, increasing new technology quilt
It is applied in nematode killing agent exploitation：One is the research and development of nematode killing agent and is sent out using to safer, environmentally friendly, efficient, holding effect direction
Open up, efficiently environment-friendly formulation turns into industry research focus to microcapsule suspending agent etc.；Two be to coordinate biostimulant, soil-repairing agent
To reach improved soil, improve the purpose of crop quality, the resultant effect of control of nematode is realized.
Biostimulant refers to that soil ecology can be improved, crop potential, enhancing crop system resistance is excited, so as to improve production
One class material of amount, quality and agricultural production efficiency.Biostimulant is typically divided into 8 classes：Humic acid, complicated organic material,
Beneficial chemical element, inorganic salts (including phosphite ester), marine algae extract, chitin and chitosan derivative, antitranspirant, trip
Isolated amino acid and other nitrogen substances etc., and wherein contain humic acid, marine algae extract, amino acid, sugar alcohol material and microbial bacteria
Agent is the most product variety of exploitation.Biostimulant is neither agricultural chemicals, is less conventional fertilizers；The target of biostimulant is
In itself, it can improve the Physiology and biochemistry state of plant to crops, improve the utilization rate of pesticidal effects and fertilizer, improve crops
The level of adverse circumstance is resisted, certain biostimulant also improves the ultimate output and quality of crops.Biostimulant is current not yet
For nematode killing agent exploitation.
Tioxazafen chemical names are 3- phenyl -5- (base of thiophene -2) -1, and 2,4- oxadiazoles are reported by Monsanto Company
The nematicide of oxadiazole classes, is mainly used in preventing and treating Plant nematode.Tioxazafen is higher to 2 instar larvaes activity, does not have to ovum
It is active.Meng Shan is registered as nematode killing agent seed treatment.Nothing in N, P element, building-up process is free of in its molecular structure
It need to use that smell is big, with serious pollution raw material, the effect of clean manufacturing can be reached, and fosthiazate has thiazole ring structure, molecule
In containing the element such as N, P, S, tioxazafen replaces the possibility of fosthiazate very big in the near future.Tioxazafen is mono-
Solely what use was still walked is the old road of traditional agricultural chemicals, does not reach improvement crop quality, realizes the purpose to nematode Synthetical prevention.Separately
It is outer to be prepared into the purpose that conventional dosage forms are also difficult to reach the slow control of holding effect.
Tioxazafen is prepared into the micro-capsule suspension containing biostimulant, in order to which tioxazafen can be more
Good is used for preventing and treating root-knot nematode, reaches improved soil, improves crop quality, improves the effect of crop anti-adversity, so that real
Now to the stereo synthesis prevention and control of nematode.
