Problems solved by technology

In the fourth issue of the Journal of Weed Science in 2008, "Screening of herbicides for controlling water hyacinth", Cai Yingjie et al. screened the herbicides for controlling water hyacinth and found that Kewuzong (bipyridinium salts) was quick-acting and died 8 days after spraying 2,4-D sodium salt , Grass leather (40% Hu. Zhongling WP) and 2M4Cl also showed good control effects, and the effect of controlling water hyacinth was between Kewuzong and Feida; butachlor and Bicao The control effect of amine w

Embodiment 1

[0026] A method for chemically controlling water hyacinth and scallop, the method steps comprising:

[0027] 1. Before collecting water hyacinth and big scallion and returning to training and raising, first expose the water in the pool to remove the bleaching powder in the water and avoid affecting the growth of the collected water hyacinth and big scallion.

[0028] 2. The collected water hyacinth and big scallion should be trained and raised in the pond for one to two weeks. After transplanting into small pots, according to the recommended dosage of 150 grams per hectare in the field, add 50 L of water. The stems and leaves of gourds and scallops were evenly sprayed with 10% mesotrione dispersible oil suspension concentrate, 15g was sprayed in each small pot, mixed with 500ml water, 3 repetitions, and a control blank.

[0029] 3. After spraying mesotrione, take pictures and record the comparison of the roots of water hyacinth and scallop before and after spraying figure 1 S...

Abstract

The invention discloses a method for chemically preventing and removing water hyacinths and pistia stratiotes.The method is completed through the first step of pretreatment, the second step of pesticide application and the third step of a check test.The method has the advantages that mesotrione can effectively prevent and treat field broad-leaved weeds and can also prevent and treat two vicious aquatic weeds, namely, the water hyacinths and the pistia stratiotes fast and effectively; a body and metabolin of the pesticide both belong to low-toxicity substances, degradation in water is fast, the activity of aquatic organisms and drinking water safety are not affected, and the aims of safe and efficient prevention and treatment with time and labor saved are achieved.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling aquatic weeds of the family Araceae and Araceae, in particular to a method for chemically preventing and controlling water hyacinth and weed. Background technique [0002] Hyacinth hyacinth, also known as water hyacinth and water hyacinth, is a perennial herb plant that floats in water or grows in mud. Its reproduction speed is fast, and the number of plants can be doubled within 5 days, and a group of 600,000 plants can be multiplied in 8 months. , 1 inflorescence can produce 300 seeds, and the seeds can survive underwater for 5 to 20 years. This grass has been flooded in 17 provinces, municipalities and autonomous regions in southern my country. It is currently one of the most harmful perennial aquatic weeds in the world. . [0003] Dale, also known as Daping, Dayelian, Furonglian, water floating lotus, fat pig dish, water cabbage, is a perennial herbaceous plant. Its reproduct...
