Embodiment 1

[0019] Example 1: Compounding of methoxyfenozide and hexaflumuron

[0020] 1. Toxicity test of methoxyfenozide and hexaflumuron

[0021] The compound synergistic test of methoxyfenozide and hexaflumuron uses rice leaf roller, diamondback moth and beet armyworm as test objects. The specific method is:

[0022] 1.1 Rice leaf roller experiment (Chaphalocrocis medina): The test drug methoxyfenozide was from Dow AgroSciences, and hexaflumuron was from Jiangsu Baoling Chemical Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The test insects are rice leaf roller larvae collected from the field, inserted into a petri dish with a diameter of 9 cm in which young rice leaves (treated with agar for moisture retention) were placed, and 5 dishes were connected for each treatment, and the potter spray tower was used at 15PSI ...

Embodiment 2

[0066] Example 2: Compounding of methoxyfenozide and flubenzuron

[0067] 1. Indoor toxicity test of methoxyfenozide and flufenuron

[0068] The test object was the beet armyworm (Laphygma exigua Hubner). The test drug methoxyfenozide was from Dow AgroSciences, and flubenzuron was from Jiangsu Zhongqi Chemical Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The test insects were collected from the larvae of beet armyworm in the field, and the larvae of the 10th generation were reared indoors with artificial feed. The chemical treatment, result investigation and statistical analysis methods are the same as the indoor virulence test of beet armyworm in Example 1.

[0069] The measurement results are shown in Table 4.

Embodiment 3

[0084] Example 3: Compounding of methoxyfenozide and chlorfluazuron

[0085] 1. Indoor toxicity test of methoxyfenozide and chlorfluazuron

[0086] The test object was diamondback moth (Plutella xylostella); the test drug methoxyfenozide was from Dow AgroSciences, and chlorfluazuron was from Shanghai Weidi Biochemical (Nanchang) Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The chemical treatment, result investigation and statistical analysis methods are the same as those of the Plutella xylostella virulence test in Example 1.

[0087] The measurement results are shown in Table 5.

Abstract

The invention discloses a pesticide composition and an application thereof on agriculture. The active ingredients of the composition comprise methoxyfenozide and a chitin synthesis inhibitor, and themass ratio of the methoxyfenozide to the chitin synthesis inhibitor is 30:1-1:20. The composition has the advantages of marked cooperative synergistic function, dosage reduction and resistance development delay. The composition can be used for the control of lepidopterous pests, and is particularly suitable for the control of rice leaf rollers, vegetable diamond back moths and asparagus caterpillars.

Description

technical field [0001] The invention relates to a pesticide composition with a synergistic effect and its application, in particular to a pesticide composition containing methoxyfenozide, and its application to control pests on plants. Background technique [0002] In the practice of agricultural production, chemical control is an important means of preventing and controlling pests in agricultural production. In the process of chemical control, the most likely problem is the emergence and development of resistance of bacteria and pests. In agriculture, resistant pests are prone to have short reproductive cycles, large reproductive numbers, and significant generational overlap. [0003] Plutella xylostella is the most important pest in southern vegetable fields. In some areas where the diamondback moth is seriously damaged, common pyrethroid insecticides (such as beta-cypermethrin, deltamethrin) and organophosphorus insecticides (such as chlorpyrifos, octylmethrin) Phosphor...
