Problems solved by technology

These agents mainly prevent and control the occurrence and development of crop viral diseases by inhibiting virus proliferation, but they cannot prevent and control piercing-sucking mouthpart pests, nor can they provide crop nutrition and regulate crop growth, so the control effect is greatly reduced

Embodiment 1

[0013] Example 1 0.5% lentinan medicinal fertilizer liquid

[0014]

[0015] The various ingredients are mixed uniformly and stirred to obtain 0.5% lentinan medicinal fertilizer liquid. The preparation was tested on rice in Nanning, Guangxi and Nanchang, Jiangxi. The experiment is summarized as follows:

[0016] (1), test materials

[0017] The above 0.5% lentinan medicinal fertilizer liquid (homemade), 0.5% lentinan liquid (Beijing Yanhua Yongle Pesticide Co., Ltd.)

[0018] (2), test method

[0019] The test is divided into three treatments, treatment 1 is 0.5% lentinan fertilizer liquid 200g / 667M 2 , Treatment 2 is 0.5% lentinan liquid 200g / 667M 2 , Spray at the initial stage of rice virus disease, and spray again after seven days. Treatment 3 is a blank control.

[0020] (3), results and analysis

[0021] From the test results of the two places, the 0.5% lentinan medicinal fertilizer liquid is slightly better than the 0.5% lentinan liquid in the prevention and control of rice virus ...

Embodiment 2

[0026] Example 2 20% moguanidine·copper acetate fertilizer WP

[0027]

[0028] The various ingredients are mixed together and passed through a 325 mesh sieve through jet milling to obtain the product. The preparation was tested on rice in Changsha, Hunan and Nanning, Guangxi. The test is summarized as follows:

[0029] (1), test materials

[0030] The above 20% moguanidine·copper acetate fertilizer WP (homemade), 20% moguanidine·copper acetate WP (Shaanxi Guofeng Chemical Co., Ltd.)

Abstract

The invention discloses a composition for preventing and treating virus diseases of crops, which is prepared from a medicament A for preventing and treating virus diseases, a medicament B for killing pests with piercing-sucking mouthparts, a plant growth regulator, a plant nutrient ingredient C, an assistant and a carrier. The medicament-fertilizer composition realizes multiple purposes, can prevent and treat virus diseases and control the main transmitting vectors of the virus diseases such as aphids, plant hoppers and the like, is capable of adjusting the growth of crops and complementing nutrition to crops, improves the disease resistance of crops while enhancing the yield and quality of crops, and can be used for preventing and treating virus diseases of crops including rice, tobacco, cucumbers, tomatoes and the like.

Description

Technical field [0001] The invention relates to the field of pesticide preparations in agricultural production, in particular to a composition for preventing and controlling crop virus diseases that integrates nutrition, insecticidal, and crop virus disease prevention and control functions. Background technique [0002] Plant virus diseases are called "cancers" of plants. The economic losses caused by virus diseases to food production, horticultural crops, and cash crops are about tens of billions each year, and the damage is becoming more and more serious. For example, in recent years, the area of ​​rice virus diseases in my country has been year by year. The expansion has caused many paddy fields to reduce or even fail. At present, the antiviral pesticides widely used in production are mostly single agents such as morpholinoguanidine hydrochloride, lentinan, ningnanmycin, aminooligosaccharin, and Junduqing, or such as morpholinoguanidine hydrochloride·acetic acid. Copper, capro...
