Embodiment 1

[0025] Embodiment 1, the preparation of various hymexazol aqueous agents and the mensuration of technical index

[0026] 1.11:3:6 preparation method of hymexazol aqueous solution

[0027] Add 1 kg of hymexazol technical substance into the container, then add 3 kg of pesticide adjuvant 06301 into the container, then add 6 kg of water into the container, then add defoamer L101 into the container and mix evenly to obtain a mixed solution. The content of defoamer L101 in the mixed solution is 50mg / kg. The mixed solution is injected into the colloid mill for homogenization under the following conditions to obtain a homogeneous solution: the gap between the stator and the rotor of the colloid mill is 2 microns, the linear speed of the rotor is 1000 rpm, and the homogenization time is 3-5 minutes. The homogeneous solution was left to stand at 40° C. for 1-2 hours to obtain a hymexazol solution, which was named 1:3:6 hymexazol solution (a 10% hymexazol solution). :3:6 Hymexazol wate...

Embodiment 2、2

[0060] Example 2. Application of 2:6:2 Hymexazol Water Agent in Banana Fusarium Wilt Control Test

[0061] 2.1 Experimental method

[0062] Brazilian banana (MusaAAACavendishsubgroupcV.Brazil) seedlings were planted in the soil of the wilt disease area (the test field before replanting was severely affected by the wilt disease, most of the plants could hardly bud, and most of the diseased plants withered and hung upside down) for 4 to 5 months. The mid-term seedlings of Brazilian bananas with a plant height of 1 to 1.5 meters have symptoms of wilt in varying degrees of yellowing and browning of the leaves, and the control test is started at this time. The experiment adopts a random block design, and three repeated areas are set up, and three small plots are randomly set up in each repeated area, which are the control treatment area, the 2:6:2 hymexazol 200 times liquid treatment area, and the 2:6:2 Hymexazol 400 times solution treatment area. There are 15 bananas in each plo...

Abstract

The invention discloses a hymexazol aqueous solution and a preparation method and application thereof to control of banana wilt. The preparation method of the hymexazol aqueous solution comprises the following step of homogenizing a mixed solution 1 or mixed solution 2 to obtain a homogenate, wherein the mixed solution 1 is composed of a hymexazol active compound, a pesticide auxiliary 06301, water and a defoaming agent, in the mixed solution 1, the mass ratio of hymexazol to the pesticide auxiliary 06301 to the water is 1 to 3 to 1, and the content of the defoaming agent in the mixed solution 1 meets the requirement of eliminating foam; the mixed solution 2 is composed of hymexazol, the pesticide auxiliary 06301 and the water, with a mass ratio of 1 to 3 to 1. The hymexazol aqueous solution disclosed by the invention has the characteristics of environment friendliness, safety, excellent performance and the like; a manufacture process is simple and the large-scale production is easily realized.

Description

technical field [0001] The invention relates to a hymexazol water agent in the field of agricultural plant protection, a preparation method thereof and its application in preventing and treating banana wilt. Background technique [0002] Banana wilt, also known as banana Panama disease, yellow leaf disease, is caused by Fusarium oxyporumf.sp.cubense, which can cause necrosis of banana vascular bundles. It is a devastating fungal disease and soil Infectious diseases are also subject to international quarantine. The occurrence and spread of the disease have caused varying degrees of damage to the banana planting industry, especially the physiological race 4 of banana fusarium wilt, which can infect almost all banana species and is the most harmful. Its typical symptoms are: diseased plant wilts, dissects pseudostem, vascular tissue turns brown, necrosis, banana root turns black, dry, and whole plant dies in the late stage of disease. The pathogenic bacteria of banana fusariu...
