Description

Agricultural chemical composition

Technical Field

The present invention relates to an agrochemical composition; in particular to the use of said compositions for controlling phytopathogenic fungi and/or harmful organisms by seed treatment or soil application methods.

Background

Active compounds of the formula I are known from WO 2007/144100.

(formula I)

Seeds of plants and roots and shoots of plants are subject to constant threats from foliar and soil insects as well as other pests and/or phytopathogenic fungi, and are the weakest link in the crop growth process; the seeds, roots and tender shoots of the plants are eaten by pests or infected by pathogenic bacteria to cause the phenomena of diseased seedlings and dead seedlings, so that the effective number of the plants per unit area can be reduced, and the yield of the crops in a large area and the quality of the crops are reduced.

Methods for controlling soil harmful pathogenic fungi and/or harmful organisms by applying seed treatment and protecting the roots and shoots of the resulting plants from harmful pathogenic fungi soil and/or foliar insects have long been known and are being continuously studied. However, treating seeds also presents a series of problems that are not always solved in a satisfactory manner. Therefore, there is a need to develop methods for protecting seeds and germinating plants which avoid the additional application of crop protection products after planting or after emergence of the plants. In addition, it is desirable to optimize the amount of active compound used so that optimum protection is provided to the seeds and germinating plants.

The control of soil-harmful pathogenic fungi and/or pests by means of soil application has long been known and is a constantly improving study. Several problems may exist with soil application methods. Agricultural compounds are not always particularly suitable for application by different soil application methods, for example by drenching, drip application, drench application or soil injection. In some cases, their pesticidal activity may be affected. Some soil applied agricultural compositions may also have leaching properties. Therefore, care must be taken to minimize surface and groundwater contamination during application. In addition, the efficacy of pesticides may vary depending on environmental conditions.

Repeated and only single application of an agricultural compound in many cases leads to a rapid selection of harmful pathogenic or harmful organisms which develop a natural or adaptive resistance to the active compounds used.

Thus, a problem facing agricultural growers is the constant threat of seeds and plant roots and shoots to harmful pathogenic bacteria and/or pests.

In situations where a mixture of soil harmful pathogenic fungi and/or pests occurs or there is a risk of developing resistance or developing resistance to currently known products, there is a need to find a more effective method of control or prevention.

Other known soil application methods are in-furrow and T-zone applications.

Biological test example

The expected effect of a particular combination of two active ingredients can be calculated using the so-called "Colby' formula" (see s.r. Colby, "marketing synergy and antibiotic Responses of pharmaceutical compositions", Weeds 1967,15, 20-22):

x is the control effect when the active ingredient compound of the formula I is used in mg/ha or mppm concentration, expressed as a percentage of the untreated control,

y is the control effect when the active component compound II is used in an amount ng/ha or at a concentration nppm, expressed as a percentage of the untreated control,

e is the control effect when using the active ingredients compounds of the formula I and compounds II in amounts of m and n g/ha or in concentrations of m and n ppm, expressed as a percentage of the untreated control,

The active compounds are applied as dry seed dressings. By mixing the active compound alone or in combination with finely ground minerals, a finely powdered composition is obtained which is uniformly distributed over the surface of the seed.

When the seeds are mixed, the medicaments are mixed into slurry according to the designed dosage, then the seeds and the liquid medicine are shaken in a closed glass flask for 3 minutes, after the seeds are evenly coated with the medicine, the seeds are poured out and spread out to be placed in a ventilation position, and the seeds are sowed after being dried. (the ratio of the amount of the syrup to the seeds is 1: 100)

Adopting an artificial inoculation mode, and preparing the fine soil and the head smut fungus spore powder into 0.1 percent of fungus soil according to a ratio of 1000:1 for later use. Corn is sown by a hole sowing method, and 50g of 0.1% fungus soil is covered in each hole after sowing.

After the corn is sowed for one week, the emergence condition of the corn is observed at any time. And (4) when the symptoms are obvious after the ears are full, poor adjustment is carried out, and the occurrence condition of the maize head smut in each cell is observed and recorded.

The prevention effect calculation method comprises the following steps:

incidence (%) =

×100%

Control effect (%) =

×100%
