Contain 4 components A1, A2, B and C.
Metalaxyl-M phenylamide systemic fungicide has protection, treatment and eradicant action to disease, has in very strong
Inhale translocation, i.e., medicament enter after plant can to top, base portion and sideways conduction, thus can be with foliar spray, seed at
Reason or pouring root.
It influences seed and/or the disease insect pest type of the root of the plant that is grown up to by the seed, branch and leaf normal growth is various,
Using seed treatment agricultural chemicals be root, branch and the leaf of the plant protected seed and/or grown up to by the seed from pest and
One of most effective chemical means of harm of pathogen；Make seed with the novel pesticide of not cross resistance and/or by the seed
Root, branch and the leaf of the plant grown up to are a good solutions from the harm of pest and pathogen；Other methods are such as
Crop structure adjustment, different pesticide rotations etc., in actual mechanical process, it is difficult to play apparent effect.Single compound is made
There are relative specificity, prevention spectrum to be not quite similar with target, single dose use easy tos produce drug resistance, and dosage is increasing, Bu Nengman
Foot reality needs, and there is also exclusive use similar problems for Binary mixture, although it makes moderate progress, thus it is urgent to a certain extent
Need the appearance of novel built agricultural chemicals.
Root system is the general name of one plant of plant whole root, also referred to as root, and root system is the water in plant absorption root growth environment
Divide, the major organs of nutrient, inorganic salts；The major function of root has：Make plant stability in the soil, storage energy resource, such as
Carrot and beet absorb moisture and minerals, round-trip stem transport moisture and minerals from soil；Root stores plant
Food (energy resource), these foods or used by root, or be digested absorption, postdigestive product through strangling skin tissue transmission
Part more than to plant soil；It can make the food of the mankind after the root harvest of some plants；Point of the plant hormone in root
It is synthesized in raw tissue, aerial part is passed up to through xylem, to promote the growth of plant to send out the region between the heart and the diaphragm；Root system is impaired, directly
Affect the healthy growth of plant.Plant stress tolerance refer to plant growth adverse environmental factor tolerance, as cold resistance, drought tolerance,
