The present invention is aimed at providing: an agrochemical composition for soil treatment which, in a soil treatment of farmland with pyroxasulfone, not only can inhibit or reduce crop injury caused by absorption into cultivated crops, without being influenced by heavy rainfall, soil type, seeding depth and the like, but also is highly safe and has a broad herbicidal spectrum; and a pest control method using the agrochemical composition. The agrochemical composition for soil treatment contains pyroxasulfone and a masking substance that masks the pyroxasulfone, in which the pyroxasulfone is microencapsulated in or coated with the masking substance.

The present disclosure relates to a solid state form of Pyroxasulfone, processes for preparation thereof and agrochemical compositions thereof.

The invention belongs to the technical field of pesticides, and specifically relates to a type of substituted-isoxazoline-containing aromatic compound, preparation method therefor, herbicidal composition and use thereof. The compound is as shown in general formula I:

##STR00001##

Wherein, Q represents

##STR00002##

Y represents halogen, halogenated alkyl or cyano; Z represents halogen; X.sub.1, X.sub.2 each independently represent hydrogen, halogen, alkyl, etc.; X.sub.3 represents halogen, cyano, etc.; X.sub.4 each independently represents —COOR.sub.5 or -alkyl-COOR.sub.5; R.sub.5 each independently represents hydrogen, alkyl, etc.. The compound has excellent herbicidal activity against gramineous weeds, broadleaf weeds, and so on even at low application rates, and has high selectivity for crops.

The present invention provides compositions comprising herbicidally active compounds (A) and (B), where (A) represents one or more compounds of the general formula (I) or their agrochemically acceptable salts [component (A)],

##STR00001##

and (B) represents one or more herbicides [component (B)]. The application furthermore relates to a method and to the use of the herbicidal composition according to the invention for controlling harmful plants or for regulating growth.

Herbicides, systems, and methods for inhibiting germination of a root parasitic plant are provided. In particular, the herbicide includes an active compound represented by Formula I. In this regard, the active compound is selected to bind to an active site of strigolactone receptors in seeds of the root parasitic plant.

There is provided an agricultural chemical (in particular, a herbicide). A pyridazinone compound of the following Formula (1):

##STR00001##

[wherein W.sup.1 and X are each independently an oxygen atom or a sulfur atom; R.sup.1 and R.sup.2 are each independently such as C.sub.1-6 alkyl; R.sup.3 is such as D-1 to D-8; Y.sup.1 is such as a halogen atom; G is such as a hydrogen atom; Z.sup.1 is such as C.sub.1-6 alkyl; n is an integer of 0, 1, 2, 3, or 4; p5 is an integer of 0, 1, 2, 3, 4, or 5; p4 is an integer of 0, 1, 2, 3, or 4; and p3 is an integer of 0, 1, 2, or 3] and a herbicide including the same.

The present invention relates to a novel and synergistic agrochemical combination. The present invention provides agrochemical combination comprising a synergist and an herbicide or a fungicide and compositions thereof especially for controlling weeds and fungi.
