Abstract

PROBLEM TO BE SOLVED: To obtain the subject composition capable of exhibiting on outstanding effect on blast in rice farming, having sufficiently controlling effect on disease damage of paddy-rice plant by a row lateral application in a paddy field by making the composition include a tetrachlorophthalide and a fertilizer. SOLUTION: This composition comprises (A) 4,5,6,7-tetrachlorophthalide of the formula of the formula and (B) a fertilizer (e.g. nitrogenous fertilizer such as urea, ammonium nitrate, etc., phosphatic fertilizer such as calcium superphosphate, double superphosphate, etc., or potassium fertilizer such as potassium chloride, potassium sulfate, etc.). Preferably the content of the component A is 25-0.0001 wt.% calculated as the amount of an active ingredient. The composition is obtained, for example, by feeding 50-99.9 pts.wt. of granular or massive fertilizer into a blender free from a grinding element, spraying an aqueous solution containing 0.1-5 pts.wt. of a tacky agent in a blending operation process to uniformly distribute the tacky agent to the surface of the fertilizer and blending the mixture with a material containing 1-50 wt.% of the compound of the formula formulated into a powdery state.

BACKGROUND OF THE INVENTION Among rice diseases, blast (an blast which occurs on leaves is called leaf blast and a blast which occurs on ears is called ear blast) is an important disease to be controlled. can give. In particular, ear blast has a significant influence on the yield because paddy rice to be harvested becomes sterile or incompletely rice. In addition, leaf blast disease suppresses the growth of the diseased strain and delays heading, resulting in a decrease in the number of effective ears and the weight of polished rice per ear. Furthermore, since the diseased site of leaf blast becomes a site of spore formation which is a source of infection of ear blast, the occurrence of leaf blast will induce the occurrence of ear blast. Germination of conidia of blast fungus and invasion and spread of mycelia of blast fungus progress rapidly under climatic conditions of 20 to 25 ° C and long-term rainfall. Conventionally, as a method for controlling blast, in Honda, a powder for blast control is sprayed on foliage several times, or a granule is applied several times on the water surface.

However, it is difficult to predict the time of occurrence of blast, and many times of chemical treatments for controlling blasts are heavy labors and heavy burdens for farmers. In addition, blast disease occurs under the weather conditions where rainfall continues for a long time.
It spreads rapidly, and on the other hand, since the chemical treatment for its control must be performed during the rain, it is difficult to perform the treatment in a timely manner, and in the conventional method, the control effect is not sufficient. It was not something.

Test Example 1 When seedlings of rice (cultivar: Koshihikari) are transplanted into a plastic pot (diameter 16 cm), 1800 mg of the composition of the present invention produced in Production Example 1 (9.0 mg as an active ingredient of agrochemicals, N component) 252 mg as P, 36 mg as P component, and 306 mg as K component).
A straight line was applied to a straight soil passing through the position of 5 cm and having a depth of 5 cm in the form of stripes, to thereby obtain a treated section 1 of the composition of the present invention. In addition, instead of the composition of the present invention, 10 parts of 180 mg of granules containing Compound A (the above-mentioned “Hokuko Labside wettable powder” (manufactured by Hokuko Chemical Co., Ltd., active ingredient of agrochemicals: 50% by weight)) is contained. To an acetone solution, 27 parts of bentonite and 63 parts of fabasami clay are added, pulverized and mixed well, water is added and kneaded well, and the mixture is granulated and dried.

Instead of the composition of the present invention, 1800 mg of a fertilizer composition containing no pesticide.
(252 mg as N component amount, 36 m as P component amount
Except for using 306 mg as the amounts of the g and K components), a lateral treatment was carried out in the same manner as in the treated section 1 of the composition of the present invention to obtain a control section 2. After the above treatment, each test pot was submerged to 3 cm above the soil surface, and then each test pot was placed in a glass greenhouse to continue cultivation of rice. On the 15th day after rice transplantation, a container made of a transparent film for agricultural use having a length of 2 m, a width of 1.9 m and a height of 1.2 m was set in a greenhouse, and each test pot was placed therein, and blast disease was prevented. Pots (diameter 8 cm) in which the diseased rice seedlings were planted were placed in the vicinity of each test pot and used as a source of blast infection. The container was sealed for about 8 hours and 30 minutes per day, the container was filled with steam using a steam generator, the humidity in the container was kept at 100%, and the container was opened at other times. . On the 23rd day after the transplantation, each test pot was taken out of the container and cultivation was continued in a glass greenhouse. On the 33rd day after the transplantation, the incidence of leaf blast in each section was calculated. The control value of the group 1 and the relative value of the control value of the group 1 treated with the composition of the present invention to the control group 1 were calculated. The disease degree of leaf blast is the index of the upper second leaf of rice. No disease: 0 Less than 5% of leaf area is affected: 0.5 6 to 10% of leaf area is affected: 1 to 11 of leaf area 25% is diseased: 2 26 to 50% of leaf area is diseased: 4 51 to 100% of leaf area is diseased: 8, and the total value of indices is calculated.

The control value was calculated as follows: control value = 100 × ((degree of disease in control group 2−degree of disease in each group) / degree of disease in control group 2). The relative value of the control value of the control composition treated section 1 of the present invention to the control section 1 was expressed by the following formula (3).

Table 1 shows the results. As is clear from Table 1, remarkable suppression of leaf blast was observed in the treated section 1 of the composition of the present invention as compared with the control section 1 and the control section 2.
