Problems solved by technology

Because wheat cyst nematodes overwinter in the soil in the form of eggs in cysts, a single control technology is not ideal. The recognized nematicides aldicarb and carbofuran are banned in production due to their high toxicity. rarely sold on

Embodiment 1

[0016] The present invention comprises method steps as follows:

[0017] a The disease-resistant wheat variety Wenmai No. 4 was used;

[0018] b. Use the nematicide Ethoprophos during the sowing period. The treatment method is to use 15Kg / hm of the nematicide during wheat sowing 2 The dosage is applied before plowing, and then poured into the soil;

[0019] c Sowing date: Appropriately late sowing, according to the actual situation in the region, the sowing date should be later, and the early sowing wheat is severely affected;

[0020] d Timely irrigation: The wheat seedling stage, overwintering, and turning green jointing stage are three critical periods, and timely irrigation should be possible in the early and middle stages of wheat growth when drought occurs.

Embodiment 2

[0022] The present invention comprises method steps as follows:

[0023] a using the disease-resistant wheat variety Space 6;

[0024] b. Use the nematicide Ethoprophos during the sowing period. The treatment method is to use 30Kg / hm of the nematicide during wheat sowing 2 The dosage is applied before plowing, and then poured into the soil;

[0025] c Sowing date: Appropriately late sowing, according to the actual situation in the region, the sowing date should be later, and the early sowing wheat is severely affected;

[0026] d Timely irrigation: The wheat seedling stage, overwintering, and turning green jointing stage are three critical periods, and timely irrigation should be possible in the early and middle stages of wheat growth when drought occurs.

Abstract

The invention discloses a comprehensive control method for a wheat cyst nematode. The method includes the following steps: a, a wheat breed of Wenmai 4 or Taikong 6 that resists diseases is adopted; b, a nematocide ethoprophos is adopted during a seeding period and the processing method is to broadcast the ethoprophos with a dosage of 15 to 45Kg / hm<2> before plowing during a wheat seeding period and then turn over thereof into the soil; c, late broadcasting is adopted and the broadcasting period can be late according to the actual situation of the area for the early broadcasted wheat has a heavier disease; d, timely irrigating: the seedling stage, the overwintering as well as the reviving and jointing stage of wheat are three key stages which can be irrigated in time during the prophase and the early time of the metaphase of wheat growing. As adopting the method and steps, the invention has strong pertinence and good effect. Due to field experiments, the invention has no harm on wheat growing and the comprehensive control measure can ensure the control effect of wheat cyst nematode to reach about 90 percent.

Description

technical field [0001] The invention relates to a method for preventing and controlling crop diseases and insect pests, in particular to a method for comprehensively preventing and controlling wheat cyst nematode disease. Background technique [0002] Cereal cyst nematode (Heterodera avenae) is a plant-parasitic nematode that mainly harms wheat crops such as wheat, oats, barley and rye, and causes losses of up to 10% to 30% or even more than 50% of wheat. Because wheat cyst nematodes overwinter in the soil in the form of eggs in cysts, a single control technology is not ideal. The recognized nematicides aldicarb and carbofuran are banned in production due to their high toxicity. There are few for sale on the Internet. Wheat cyst nematode is a new disease in our country, which has caused serious damage to crops in our country. Contents of the invention [0003] The purpose of the present invention is to provide an integrated control method for wheat cyst nematodes that ca...
