Susceptibility of Phytoseiulus persimilis Ath

Susceptibility of Phytoseiulus persimilis Ath. (Phytoseiidae) mite predators to some pesticides. Stamenkovic, Tomislav; Peric, Pantelija (Inst. Plant Prot., Belgrade, Yugoslavia). Zast. Bilja, 35(170), 317-21 (Serbo-Croatian) 1984. CODEN: ZABIAY. ISSN: 0372-7866. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Dipping P. persimilis from a lab. population in greenhouse pesticides for 10 s showed low toxicity (0-29% mortality) of compds. such as fenbutatin oxide [13356-08-6], tetradifon [116-29-0], bisclofentezine [74115-24-5], cyhexatin [13121-70-5], propargite [2312-35-8], pirimicarb [23103-98-2]. Medium toxic pesticides included amitrax [41483-43-6], binapacryl [485-31-4], dicofol [115-32-2], dialifos [10311-84-9], phosalone [2310-17-0], and carbendazim [10605-21-7]. Mortalities ranged 30-69%. Highly toxic pesticides included, e.g., bromopropylate [18181-80-1], diazinon [333-41-5], carbaryl [63-25-2], demeton-S-methyl [919-86-8], azinphos methyl [86-50-0], dimethoate [60-51-5], and phosphamidon [13171-21-6]. Mortalities from these compds. ranged 70-100%.

Gas chromatographic determination of residues of bromopropylate and two of its degradation products in honey

Gas chromatographic determination of residues of bromopropylate and two of its degradation products in honey. Formica, Giuseppe (Agro Div., Ciba-Geigy Ltd., Basel 4002, Switz.). J. Assoc. Off. Anal. Chem., 67(5), 896-8 (English) 1984. CODEN: JANCA2. ISSN: 0004-5756. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) An anal. procedure is described for detn. of bromopropylate (BP) [18181-80-1] and its main degrdn. product 4,4'-dibromobenzophenone (BBP) [3988-03-2] in honey. The method also allows the detn. of 4,4'-dibromobenzilic acid (BBA) [30738-49-9], a potential intermediate to BBP. The method involves dissoln. of the honey in water and sepn. of BP and BBP from BBA on a partition column. BP and BBP are further cleaned up and sepd. on a silica gel column and detd. by gas chromatog. (GC) with electron capture (EC) detection. BBA is oxidized with K2Cr2O7 to BBP, which is partitioned into CH2Cl2 and further cleaned up on a silica gel column before detn. by GC with EC detection. The method is sensitive to 0.02 mg BP or BBP/kg and 0.023 mg BBA/kg honey.
