Embodiment Construction

[0008] The present invention spreads 160 ± 10 ml of fenpropathrin with a concentration of 18%-22% per acre about one day before and after planting lotus roots to eliminate the lotus root maggots on the lotus seedling felt and the larvae overwintering in the field. 30cm, water retention for 7-15 days, not only kills the overwintering maggot larvae, but also cures the lobster.

[0009] Around May 15, 160±10ml of fenpropathrin with a concentration of 18%-22% per mu was applied to the larvae crawling in the lotus root field, and the accumulated water was 15-30cm, and the water was kept for 7-15 days to kill Lotus root maggot larvae and lobster.

[0010] The lotus root period around July 20, at this time, the prevention and control of lotus root maggots is more critical. When the lotus root enters the fruiting period, the lotus maggots will drill underground along the lotus stalks and penetrate into the ground, endangering the lotus root. In the thin water layer in the field, the ...

Abstract

The invention relates to a lotus rhizome maggot-kill method, in particular to a lotus rhizome maggot-kill method of fenpropathrin. The squab larva can creep in the lotus rhizome field in May, so the fenpropathrin in 18 to 22 percent concentration is distributed per mou before or after the day of planting the lotus rhizome to kill the lotus rhizome maggot on the young lotus rhizome felt and the overyear larva in the lotus rhizome field and then seeper and water keeping are carried out. When the maturation period of the lotus rhizome is coming, the lotus rhizome maggot goes into the ground along the lotus stem, so the fenpropathrin in 18 to 22 percent concentration is distributed per mou to kill the lotus rhizome maggot on the young lotus rhizome felt and the overyear larva in the lotus rhizome field, and then seeper and water keeping are carried out. Simultaneously the larva of lotus rhizome maggot and the lobster are killed. The applicant carried out the invention in the lotus rhizome field in hanchuan city for three years and the tests verify that the invention can kill the lotus rhizome maggot effectively and the kill rate reaches a hundred percent. The farm chemical verification office is invited to check the pesticide residue on the lotus rhizome by agriculture bureau of hanchuan city and the result is that the fenpropathrin is less than 0.5 and the residue of the cypermethrin, the sumicidin and the cyfloxylate is eligible, so the invention is verified to be nonhazardous.

Description

technical field [0001] The invention relates to a method for killing lotus root maggots. Background technique [0002] Lotus root maggot has another name called root-eating golden needleworm. In addition to harming lotus roots, it also harms rice roots. Due to the harm of lotus root maggots, the production of lotus roots has been reduced by more than 50%. Elimination of lotus root maggots is an urgent problem to be solved in the current production of pollution-free lotus root. In the past, textbooks advocated the use of "carbofuran" to control lotus root maggots. "Carbofuran" is a highly toxic pesticide. Farmers use it at high temperatures. Most people will suffer from acute drug poisoning after applying the pesticide. Not only will it cost thousands of yuan for medical treatment, but those who are deeply poisoned will even die. Although there were no problems at the time, when lotus roots were on the market and the green lotus roots were dug in a hurry, skin itching and ...
