Embodiment 1

[0019] Example 1: The root absorption of p-fluorophenoxyacetic acid to treat rice reduces the survival rate of rice planthopper nymphs

[0020] In this example, the concentrations of p-fluorophenoxyacetic acid used are 1 mg / L and 10 mg / L. The rice used is nutrient solution cultured rice, planted on a single plant; the treatment method is to add p-fluorophenoxyacetic acid to the rice nutrient solution to a final concentration of 1mg / L or 10mg / L, and use the nutrient solution without adding p-fluorophenoxyacetic acid as control. After 12 hours of p-fluorophenoxyacetic acid treatment, put a special glass cover (diameter 4cm, height 8cm, and 48 small holes with a diameter of 0.8mm evenly distributed on the wall of the tube) on each rice stalk, and insert the newly hatched brown planthopper or There were 15 white-backed planthopper nymphs, and the top of the glass cover was sealed with a round sponge. The experiment was carried out in an artificial climate room with a temperature...

Embodiment 2

[0021] Embodiment 2: p-Fluorophenoxyacetic acid stem and leaf spray treatment improves the resistance of rice to rice planthopper nymphs

[0022] In this example, the concentrations of p-fluorophenoxyacetic acid used are 20 mg / L and 100 mg / L. The rice used is nutrient solution cultured rice, planted on a single plant; the treatment method is to prepare p-fluorophenoxyacetic acid with water to a corresponding concentration (20mg / L or 100mg / L), and then use a small sprayer to spray the rice stems and leaves; as comparison. After the fog droplets on the rice stems and leaves are completely dried up, put a special glass cover (4cm in diameter, 8cm in height, 48 small holes with a diameter of 0.8mm evenly distributed on the wall of the tube) on the rice stems, and insert the newly hatched brown planthopper or white back There were 15 planthopper nymphs, and the top of the glass cover was sealed with a round sponge. The experiment was carried out in an artificial climate room with...

Embodiment 3

[0023] Example 3: p-Fluorophenoxyacetic acid itself has no effect on the survival of rice planthopper

[0024]In order to exclude the possible influence of p-fluorophenoxyacetic acid itself on the survival rate of rice planthopper nymphs, in this example, the gastric poisoning and contact killing effects of different concentrations of p-fluorophenoxyacetic acid itself on rice planthopper nymphs were measured. In the experiment of determining the gastric toxicity of p-fluorophenoxyacetic acid on rice planthopper nymphs, p-fluorophenoxyacetic acid with a concentration of 5, 20, and 50 mg / L was selected to be added to the artificial diet of planthoppers. Artificial feed with phenoxyacetic acid. Artificial feed containing different concentrations of p-fluorophenoxyacetic acid (20 μL at each end) wrapped with Parafilm sealing film was placed at both ends of a glass double-way tube with a diameter of 4 cm and a height of 8 cm, and 15 newly hatched white-backed fly were added to the ...

Abstract

The invention discloses a method for stimulating rice induced insect resistance. Nilaparvata lugens (St l), Sogatella furcifera (Hrovath) and Laodelphax striatellus (Fallen) are involved. By means of p-fluorophenoxyacetic acid, the resistance of rice to rice planthopper is improved, and then the damage of rice planthopper to rice is reduced. By applying p-fluorophenoxyacetic acid with certain concentration to rice, the induced resistance of rice to rice planthopper is produced, and the survival rate of rice planthopper nymph is remarkably decreased.

Description

technical field [0001] The present invention relates to the field of rice induced insect resistance, specifically, relates to a method for stimulating rice induced insect resistance. Background technique [0002] With the increase of the global population and the reduction of arable land, people's requirements for grain yield are getting higher and higher. The loss caused by various insect pests to the world's grain production accounts for 10-30% of the total production, and the severe disaster year causes no harvest. Rice is one of the three major food crops in the world. Nearly half of the world's population, including almost the entire population of East and Southeast Asia, feeds on rice. The perennial rice planting area in my country is about 30 million hectares, accounting for 40% of the country's total grain output. Rice production is directly related to my country's food security, farmers' income increase and social stability. Rice planthoppers, including the brown...
