The present invention is a composition that can form an edible film or an edible liquid coating that can be applied to the surface of fresh fish (fillets or cuts) or fresh seafood. The present invention acts as a physical barrier preventing oxygen, water and microorganisms from entering the food product, and also acts as a bacteriostatic and antioxidant agent.

Disclosed is a combination of encapsulated, in particular micro-encapsulated phenothrin and emulsified prallethrin in water, preferably in a ratio of 10:1. This combination has excellent suitability for use as an insecticide. The suitable concentration is about 0.1% by mass of phenothrin and 0.01% by mass of prallethrin. The insecticide is used at a concentration of 20 ml/m.sup.2 to 60 ml/m.sup.2 on non-porous surfaces or in a concentration of 40 ml/m.sup.2 to 120 ml/m.sup.2 on porous surfaces. Despite the low amounts of active ingredients, the insecticide shows a rapid knockdown effect and a prolonged depot effect.

Insect control nanobodies are provided. Accordingly there is provided a nanobody which specifically binds to an insect polypeptide selected from the group consisting of: a polypeptide comprising a chitin binding domain (CBD), V-ATPase subunit c, trehalase, cytochrome p450 monooxygenase, chitin deacetylase, chitin synthase and NPC1 sterol transporter, wherein binding of the nanobody to the insect polypeptide confers an insect control activity to the nanobody. Also provided are polynucleotides encoding the nanobody, host cells expressing the nanobody and methods of using it.

The present invention is aimed at providing a weed control method and a mixed agrochemical composition for soil treatment, which, in a soil treatment of farmland with pyroxasulfone, not only can inhibit or reduce crop injury caused by absorption into cultivated crops, without being influenced by heavy rainfall, soil type, seeding depth and the like, but also are effective against a wide range of weed species. The weed control method includes a soil treatment step of performing a soil treatment on farmland with an agrochemical composition for soil treatment, which contains pyroxasulfone, and with a protoporphyrinogen oxidase inhibitor, simultaneously or sequentially, the method being characterized in that the agrochemical composition for soil treatment further contains a masking substance that masks the pyroxasulfone, and the pyroxasulfone is microencapsulated in or coated with the masking substance. The mixed agrochemical composition for soil treatment is characterized by containing the agrochemical composition for soil treatment and a protoporphyrinogen oxidase inhibitor.
