Embodiment 1

[0014] Example 1: Both dacetam and 1,3-dichloropropene were processed into sustained-release dosage forms for use. The specific usage method is as follows: first, 1,3-dichloropropene liquid preparation (such as: 93.6% 1,3-dichloropropene emulsifiable concentrate) is adsorbed with activated carbon, and then the activated carbon is wrapped with polyvinyl alcohol to obtain 1,3 - Solid sustained release formulation of dichloropropene. Then mix the above-mentioned solid sustained-release agent with datamon solid preparation (such as: 98% datamon granules) at the ratio of active ingredient DZ: 1,3-D=0.01-0.99:0.99-0.01 before use.

Embodiment 2

[0015] Embodiment 2: using datron and 1,3-dichloropropene successively respectively. Concrete use method is: the first step, apply cotton wool (such as: 98% cotton wool microparticles), earlier rotary plowing soil before spraying, and then rotary tilling soil after spraying, make cotton wool and soil mix evenly; Second The first step is to apply 1,3-dichloropropene (such as: 93.6% 1,3-dichloropropene emulsifiable concentrate), which can be injected by manual or motorized soil disinfection machine, and can also be applied by drip irrigation equipment; the third step is to cover the film Fumigate for about 2 to 4 weeks; the fourth step is to open the air for about 1 week, and after the lettuce seed germination test qualitatively judges that there is no chemical residue, it can be planted.

Embodiment 3

[0016] Example 3: Cotton and 1,3-dichloropropene were applied simultaneously using matching disinfection machinery. The specific method of use is: adopt a matching disinfection machine (see attached Figure 4 ), at the same time of spreading the solid preparation of damelong (such as: microgranule, etc.), you can spray or inject 1,3-dichloropropene liquid preparation (such as: emulsifiable concentrate, etc.), and then rotate tillage to mix the agent and soil evenly After that, the film covering measures can be carried out at the same time, and the fumigation process can be completed in an integrated way.

Abstract

The invention relates to mixed application technology of a compound micofume (DZ, whose common name is dazomet) and 1,3-dichloropropene (1,3-D) for controlling root-knot nematodes, soil-borne pathogenic fungi, and weed activity. The mixed application technology is suitable for pre-seeding soil disinfection of crop fields of vegetables, strawberries, flowers, gourds, nurseries, orchards, tea gardens, vineyards, forest trees, Chinese herbal medicines, and the like, and can effectively control southern root-knot nematodes, main soil-borne pathogenic fungi, main gramineae and broad-leaf weeds, and the like.

Description

technical field [0001] The present invention relates to the mixed use technique of controlling root-knot nematode, soil-borne pathogenic fungus and weed active compound dasyron and 1,3-dichloropropene, which is used for preventing and controlling vegetables, strawberries, flowers, melons, nurseries, orchards and tea gardens , Vineyards, forests, Chinese herbal medicines and other crop fields before planting soil disinfection, effective control of root-knot nematodes, main soil-borne pathogenic fungi, main gramineous and broad-leaved weeds, etc. Specifically, the effective ingredients of pesticides, triamron and 1,3-dichloropropene, are mixed and used in different proportions and in different ways. Background technique [0002] In the past ten years, with the adjustment of agricultural planting structure, protected cultivation has developed rapidly in our country. The national protected area has exceeded 2 million hectares. As an important agricultural measure to increase f...
