Embodiment 1

[0018] Example 1 Preparation of 50% boscalid water dispersible granules

[0019] Boscalid 50%

[0020] Dispersant--sodium lignosulfonate 5%

[0021] Wetting agent - sodium lauryl sulfate 3%

[0022] Disintegrant 8%

[0023] Binder 1%

[0024] Kaolin supplemented to 100%

[0025] According to the above formula requirements, the boscalid original drug, dispersant, wetting agent, disintegrating agent and fillers are air-pulverized together, and then additives such as binder are added to obtain a semi-finished product, which is quantitatively sent into the stream Bed granulation, followed by drying and sieving to obtain 50% boscalid water-dispersible granules.

Embodiment 2

[0026] Example 2 Preparation of 30% boscalid suspension

[0027] Boscalid 30%

[0028] Dispersant NNO 3%

[0029] Agricultural Milk OX-656 1.5%;

[0030] Nongdai 0201B 1.0%;

[0031] Agricultural Milk 1601 1.0%;

[0032] Nongru 700# 0.5%;

[0033] Ethylene glycol 5.0%;

[0034] Defoamer 0.2%

[0035] Water to make up to 100%

[0036] According to the requirements of the above formula, put boscalid, dispersant, and emulsifier into the mixing tank for high-speed shear mixing, then add defoamer, antifreeze, etc., and grind them in a sand mill to make the particle size Below 5 mm, make 30% boscalid suspension.

Abstract

The invention provides a bactericide taking boscalid as an effective component and for rice field, wheat field and corn field. The bactericide employs boscalid as the effective component, and proper auxiliary agents and carriers are added. The bactericide can be prepared into various forms such as water-dispersion granules, suspending agents, microcapsule suspending agents, dispersible-oil suspending agents, oil suspending agents, wettable powder, film-spreading oil agents, emulsion in water, micron emulsion, granules, effervescent tablets and the like. The bactericide used for rice field, wheat field and corn field has good control effect on main fungous diseases of rice, wheat and corn, does not cause drug resistance, is obvious in yield increase effect, is safe to rice, wheat and corn, is low in toxicity and residues, and is suitable for popularization and application in agriculture production.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an agricultural fungicide containing boscalid, which is mainly used for preventing and controlling plant fungal diseases in paddy fields, wheat fields and corn fields. [0002] Background technique [0003] Corn, rice and wheat are the main grain crops in my country, with an annual planting area of ​​more than 1.3 billion mu, accounting for 80% of the country's grain crop planting area. Corn, rice and wheat are faced with various fungal diseases during the whole growth and development process. The fungal diseases of the three major crops have various types, complex symptoms, rapid spread, serious damage and compound occurrence, which makes the prevention and control more difficult. Crop yield and quality pose a serious threat. At present, the resistance of commonly used fungicides develops rapidly, leading to a continuous increase in dosage, which has adverse effects on crops and the ...
